I have more acting credits than anything else (I am an actor). Yet, stunt work is listed first. Also, two of the film posters that used to have my character names under them now are credited as stunt performer. How do I get this reversed back to the way it was originally?
You have two different stunt jobs listed on each of two films: stunt coordinator, and stunt performer, on both Wintrone and Impact. That gives you, for IMDb's counting purposes, a total of 4 stunt credits, even though your page says "Stunts (2 credits)". By contrast, you have 3 acting credits, so that makes Actress your #2 job category after Stunts.
In the meantime, the only advice I can give you would be to get 2 more acting credits before you get any more stunt credits. That will make Actress your #1 job category again, and it should also affect how the descriptions under the posters on your page are shown.
