Dolphin not remembering drive's password

Hi,

I’ve installed Manjaro on a separate drive and the windows drive (which is separate) is encrypted. When I try to mount the drive, dolphin asks me the key even if I select remember password.

When I check kwallet, the password is stored but without any name on it. What can be done to make it associate the password with this drive?

Edit: uploaded screenshot now that forum allows me.
