XF 2.2 Outdated template wont go away

Hello!
I have a parent and a child. In the child I created the file extra.less but what I do, the file dont go away from the outdated templates, it's a bit annoying

Revert the template in the child style so it inherits from the parent, then reapply any specific changes in the child style template.

If I revert it, make a plain extra.less in the parent, save it, go to the reverted from the child, added code and then is the parent in the outdated template.
I could do it all in the parent but wouldnt be the best option.
