How to delete top level of predefined value?

I just bought a module from vendors here and it mess upp a lot i think. The module is adding a Top level on predefined values here and how to delete them. I tried but i can't. It's the same level as Body type and so on.

Unfortunately, the way the predefined value list is, you can not delete entries from database itself. You can try writing your own SQLto delete what you need to and see if that works.

Ok. thank you i will wait for the vendor to wake up tomorrow if he working. And let him fix the module for me.
