Hi Samyell77, I found that if the original component has ever existed in the model I am wanting to copy the newly named component into, even with old components deleted and purged, the model seems to recognise the newly named component, and gives it its old name.

Using fresh files, with no old components lurking from templates, seemed to work for me. I hope that helps you?

Samyell77, did you ever find a solution to the names not sticking to components? I am having the same issue when copy and pasting from one model to another, something I have done in the past without an issue.
