I made a homebrew Macaw and used it as a pet, with +2 on performance. It says on the character sheet in the pet section that is has +0, but when I checked to homebrew page for the macaw, it was +2. Why does it show +0 on the character sheet?

There a few things that might be the problem, perhaps posting the sheet can help:

1. Either you didn't save the editor properly  for the edited macaw stat block with the blue save button

2. The charisma of the macaw is a 6 which is a -2 prompting a +0

3.Refresh your character sheet it just didn't load the update yet (wait a total of 1 - 5 mins for it to update)

4. Open a new beyond tab, exit the old one, and open character sheet to check if it updated again

5. It might actually be a bug

Did you put the +2 as a bonus or as an “additional” bonus? Stuff entered into the additional bonus field doesn’t register in the extras section.

It was in bonus, not additional.

The macaw has a charisma of 7, maybe that's the problem. Although outside of the character sheet, it says +2 and has all the same stats... The fact that they're the same but with different performance modifiers is strange though.

How do I fix it?

Fixed. Thanks for the help.

Oh, yeah. They got halfway into making extras actually calculate stuff to support things like the Steel Defender, but it got too complicated so they abandoned the project. That’s what caused the issue.

I got it to show +2 on the character sheet, although the normal page is +4 now so I just commented that it should be +2 on that page.

If you put a -2 in the Additional Bonus for that monster it should show the correct bonus on the monster statblock but not affect it in the Extras section. (Should)

 It worked, it shows +2 in both.
