Damage modifier increasing incorrectly on crit damage

[Blackzerker]

Good morning, I hope I'm in the right place because I cannot figure out what is happening here. This on PF1e, and the only extension I'm running is one that changes the theme.
As per the below photo you can see that it calculates my +2STR accurately for normal damage rolls and crit damage rolls. Then when I apply my Inspired rage which gives +8 STR it has no problem calculating the number as +6 for normal damage rolls.
This is where it gets weird, when I roll crit damage with Inspired rage active it suddenly boosts my modifier up to a total of +20 instead of the expected +12 from a 6*2
I hope this makes sense and I'll be happy to provide any further information and even the character file if needed. Any help to confirm I'm not losing my mind is appreciated.

EDIT: I've attached the character file, and this is on Classic not Unity.

If you can export the character and provided here we can check it over. I think it might be an issue with the effect line, but best to do testing with the actual character. My tests aren't replicating what you are seeing.

Here, hopefully you can find something, good luck and thanks for looking
I should mention too this is on Classic not Unity

Unfortunately, we are no longer supporting classic as of June 2021.

We aren't even set up to make changes to the code for that system anymore; only provide the last snapshot of files as of that date.
