As a collaborator I have no powers to delete discussions created by me

[genis-fornes]

Hi!
I appear as a collaborator and not as a maintainer, also for the discussions I create myself. As a collaborator i don't have the powers to delete the solved discussions we create. The delete option on the lower right corner simply doesn't appear to me. Some other members of my team are maintainer and didn't do differently than I did.
Thanks in advance for any tip on how to change this!
