Armor Check Penalty isn't working

ACP isn't budging in the slightest no matter what I do, but Attack Penalty works as normal if Prof is No.

What is your current carrying capacity?  Also, check your encumbrance settings.  Settings|Sheet Configuration|Encumbrance    

I set them to ignore everything, but I thought of that and set it to Armor & Shield Only once with no progress.

If Encumbrance based On is set to "Ignore Encumbrance" or "Load Only", the sheet will set ACP=0 and Max Dex=99.  Are you seeing this even with "Armor, Shield and Load" and "Armor and Shield Only"?  I can't seem to replicate this... ;-(   Encumbrance Setting ACP Max Dex Armor, Shield and Load yes yes Armor and Shield Only yes yes Load Only N/A, 0 N/A, 99 Ignore Encumbrance N/A, 0 N/A, 99

Okay, I didn't know it did that with "Ignore Encumbrance." I can't replicate what happened with "Armor and Shield Only" either so I'll chalk it up to a mistake on my end. I wish I could set "Ignore Encumbrance" to Yes, but I'll live with it. Thank you for your help.

I would set encumbrance to "Armor and Shield Only" (which, for a class that uses armor/shield should have a minimal effect on carrying capacity) and you will still get the RAW for ACP and Max Dex.
