Soon after the positive rate call; (L) Reverser Unlocked Amber msg displayed. After leveling off at 10;000ft ran the QRH. Notified ATC/FA/Pax of our situation and turned back to [departure airport]. The second part of this report discusses the MEL for the Thrust Reverser System. I noticed after the second departure that MEL Maintenance section number 4 was not accomplished. Specifically referring to open CB B7 on CB panel-4 and collar it. Followed the QRH. Follow through with everything.
CRJ-200 Captain reported returning to departure airport after receiving a (L) Reverser Unlock amber message. Reporter noted that Maintenance may not have fully complied with the MEL.
