Different sheets for premade adventures, 5e

Running masters vault into lost mines  and players asked about the community sheet instead of the roll20 sheet. Looked it over and not bad but when i switched sheets, and even made a new game with the sheet, all the monsters didn't have any actions and if i switch the npc tab its a pretty much blank sheet. Am I doing something wrong or is the premade things only on the standard sheet?

All of the Module content is set up for the 5e OGL sheet.  The attribute names don't fully line up with the Community Contributed sheet (which is really quite old and unmaintained at this point).  Aside from hand migrating all the monsters and players, your only real alternative is the Shaped Sheet, which will read the OGL format and migrate automatically.

Thank you very much
