Can not re-create same name fixture, after "Remove fixture"

[MTF Showtechnic]

I've just seen that erasing a fixture didn't work right.
Description what I've done:
1.Add a new fixture "Xpression" with 8 Channels
2.Patched it to DMX List.
3.Gone to Subitem "Erase Fixture" and erased the "Xpression".-> It's erased from the DMX List.
4.Add a new fixture with the same Name "Xpression"
5.Software says: "Fixture already existing"
6. Looked into the Fixture File. There I can see the fixture "Xpression" and the "Xpression backup"
So I think it's a bug. At least the "Xpression" File should be erased. Or am I wrong?

BTW: I've looked into all Menu's and there german translations. Sometimes it doesn't make sense to translate "Word by word"
So I revised the last attached German File a Little bit.
I hope that's better to understand by other User's.
Here's the new one.

"Remove fixture" removes the fixture only in the drawing. For safety reasons, the personality file is not deleted.
If you decide to re-create a fixture with the same name, before that, you have manually delete the file from the fixtures folder.

Thank you for the revised German.ini file ; it will be in the next complete software version.
