Problem Modifying Vendor Url

Good morning sorry I have a problem with the URL of a seller, the problem is that I want to change its URL from "diesel-en-2" to "diesel" but it does not allow me to change it and it will show "diesel-en-2" again. Please if someone can guide me on how to make the switch and tell me why this problem occurs to me.

Another object with the "diesel" value exists in the database. If you are familiar with the phpmyadmin, check the cscart_seo_names table. It can be not only vendor, but product feature variant, category or something else

I have 4 records with the word "diesel" in cscart_seo_names table
They are:
- "diesel-blog"
- "diesel-es-2"
- "diesel-es"
-"diesel"
my question would be, how can I make the "diesel-es-2" be just "diesel"
I'd appreciate your help

At first rename last record to something else. Then rename required record in the database

try modifying the "diesel" registry to "diesel-mod" and it gives me the following message "Error: Invalid CSRF token. Please submit the form again. If you did not submit this admin request, please close this page. Need help"
Please I would appreciate some help

Did you get this error in phpMyAdmin?

Yes, that error appears when I modify the record "diesel" to "diesel-mod" within the table "cscart_seo_names" and save it, I get the message "Error: invalid CSRF token. Please resubmit the form. If you did not submit this admin request, please close this page. Need help" and the registry has not been modified and is still "diesel", this happens in the database administrator which is "Adminer 4.7.5"

I'm from Latin America, sorry if there is an error in the translation

Yes, that error appears when I modify the record "diesel" to "diesel-mod" within the table "cscart_seo_names" and save it, I get the message "Error: invalid CSRF token. Please resubmit the form. If you did not submit this admin request, please close this page. Need help" and the registry has not been modified and is still "diesel", this happens in the database administrator which is "Adminer 4.7.5"

It should be addressed to hosting administrator
