Thri-kreen chameleon carapace

After making a thri-kreen and removing the armor i noticed the chameleon carapace does not apply to the ac at all. I had to make an armor remove its properties and put the proper ac bonus in its stats to get it to reflect on his Ac statistic up top of sheet. Can someone else try this and confirm? or am i doing something incorrect?

Hi Kefrem,  I assume you are using the D&D 5e by Roll20 character sheet? If you are, Custom ACs are not baked in to the races or classes. To enable that you need to click on the "cog" next to Spells, then set up the Custom AC (middle column near the top) as appropriate for your race or class.  When you wear armor it will override the custom AC, but that override will come with a warning in the equipment section. 

ahhh ok thanks ill tinker and fix it. Never knew that.
