Q:

1 include - 2 templates - 2 different results

I have an include / embed file that is being shared across two templates. However one template is displaying a result of the channel:entries tag in the embed whilst the other refuses to display a result.
I have tried updating the channel:entries tag and the second refuses to load content from any channel at all. 
Below is the log information from template debugging:

A:

Since you're using the same embed on different templates, I guess their URLs are different from each other. The results of exp:channel:entries tags are influenced by the URL.
If you need to bypass this influence, set the dynamic parameter to no.
