Hello,
I have created a test attribute and added an attribute item. I saw no errors. I see the styles are broken a bit, could you please describe the actions step by step to catch the error? The screens would be helpful.
As for the view, deactivate all the plugins except these ones:
Slider Revolution
Elementor
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.
Best Regards
