Is it acceptable if an advisor does not include me as a co-author on presentation? I apologize if this question is redundant in some way but I was unable to find a question similar to this. 

I am a MS student (with thesis) and have an advisor who received a grant with myself as a collaborator to do a particular project. He has a hands off approach (or is just extremely busy) so I have planned, executed, analyzed the entire project. I am currently writing a manuscript that he will be a coauthor on (as the PI). 

Recently he went to a meeting put on by the group that funds the project, with a presentation about my project. However, he left my name off the title slide and had me last on the acknowledgements (with my name spelled incorrectly) and a small picture of me next to people who only made smaller (albeit important) contributions. I feel like this is wrong, but he said it's normal to only have his name and another PI (not an author) on the title slide when I brought this up. To boot, he asked me to prepare the presentation, which I did, and he took my name off deliberately. 

Am I crazy/egomaniacal? This seems wrong...

I was hoping for some opinions outside our lab group. Any thoughts would be appreciated!
There are basically two schools of thought on who should be on the title slide of a presentation: (i) everyone who has contributed, (ii) the name of the person who is actually standing in front of the audience and giving the presentation.

There is no accepted standard for which is the "correct approach". I tend to think that fields where projects only comprise 2 or 3 people use method (i), whereas more collaborative fields use method (ii) -- and I tend to think that that makes sense, because otherwise one would have to list a dozen or more people on the title slide, which is simply not very practical, and also not useful to the audience.

So I don't think that taking your name off the title slide is unprofessional or unethical in itself, even if you were the one who prepared the slides -- your adviser was, after all, the one who presented the talk and the project.

That said, if the adviser had been me, I would have made sure that you would have been prominently mentioned in the talk (and made sure that your name is spelled correctly!) but in the beginning ("Before I go through the details, I do want to mention that most of the work I am presenting here today was actually done by my student rapidCascade, and I do want to make sure that he gets the credit he deserves!") and at the end ("Before I end, let me acknowledge that many people have contributed to the work I just presented. In particular, I'd like to single out rapidCascade who has done more than any of the others.") These words may not be reflected in any of the slides, and unless you were there in person, you'd never know that this much credit was given, but it is possible to highlight someone's contributions without making this explicit in the slides.
