BULK Product Atributes NOT WORKING

I need it to work with “BULK product attributes change” but it still doesn’t work. (screenshot 1)
When I change the required attributes (screenshot 2) and click “Save”, a “Bug” occurs (screenshot 3). When I hit refresh the page, all attributes appear and nothing is changed. It has also not been changed on the products.

This “Bug” has been running for 3 months and has not been fixed with any updates. I also see that several users reported this problem a year ago and that nothing has been done since then.

Please tell me how to fix this or give me a deadline by which it will be fixed.
