Star Wars 5th Edition 2.5 Sheet

My DM found something odd with the SW5E sheet. He says that Add Global A/C Modifier that is usually found on 5e sheets is missing. We haven't been able to add certain functions to the sheet as normally, as well. We were wondering what could be done about this on our end, or if there's something in the sheet itself that didn't fully carry over? Thanks :)

Have you contacted the creator of the sheet?

Anthya the SW5e sheet is based on a 4 year old open source version of the D&D5e sheet that was modified by the original creator.  Since that time Roll20 has taken over development of the D&D5e sheet and closed the source code.  Due to this and other factors the SW5e sheet has not kept pace with the Roll20 5e sheet development.  However, a Global AC modifier is available on the sheet under the settings tab for PC's:

Thank you so much :D
