While using ams with subpar I got this issue: tingerrr/subpar#31
The template would have to allow you to remove this style specifically, or at the very least provide the outer figure context to be compatible with contextual numbering styles.
By extension, you could also not number your figures with the current chapter with ams-article either. Please report this upstream at the package repo
