Updating Category Access Via Mass Action Removes Access For All

Hello, my problem is as such:

I import products and their categories via csv, which works fine.

The only thing I need that I can't do in the csv is to set the Access level of the category. The category access level is set to "All" when it imports. So to this end I decided to use mass actions after import. I've attached a screenshot of my settings.

Essentially I filter by the category name, and in the actions I choose "Update the values", then choose "category access", and I set the type dropdown to "STRING". I've also used "INT" and it worked as well.

In the input field I put my Joomla Group ID.

When I click Process the mass action does work in the sense that if I edit one of my categories I will indeed see that the Access level is changed correctly.

The problem comes when I login via the front end with the correct user for that group (I have both User Groups and Access Levels set correctly in Joomla). When the user logs in they will see nothing. By that I mean no products. The menus and other site trappings are there, but the products will not show.

The only way to fix this is to manually edit each category and re-save it. Then everything works as normal, but then you can see that the purpose of the mass action is defeated.

What could be causing this? Is there anything in my setup that should be changed?

for some reason my file uploads kept failing. Here is a link to my mass-action screenshot.

Yes, it worked. I did it that way and the problem is now gone. Thanks.
