Hi,
Thanks for the info.
I don’t see any issue myself. I’m running the latest version of plugin, the latest version of WordPress, and the latest version of 2020.
Nothing appears broken and there are no nested tables that I can see.
There are three table groups using <table class=”form-table”> for styling and grouping.
1. The first three text fields name, slug, parent category which are WordPress defaults
2. the enhanced text description box
3. the category img and og image text fields.
All are correctly nested so there should not be any broken markup that is impacting on the appearance of the edit page.
I’m not sure what you edit page looks like but this is how it appears to me
