Hi @LeonidS

Thank you again for the response and patience.

"Yes, I mentioned reasons about, but in your case with 1 big category this issue looks more uncomfortable than usual situations."

I want to clarify that the same problem (the category cannot be modified) occurs when using the Ads module for any type of ad. That's why I think it's a module problem.

"I guess it will be released with UNA 14 stable."

Any approximate release date for UNA 14?

"You may try to use this variant for subcategories to keep main features: https://unacms.com/wiki/Browseable-categories"

Great! thank you so much.

Regards.
