Mirror and then Move

I mirrored a curve and then tried to move it. The move-tool doesn’t “see” it. Is this how it is?

And visa versa: I moved a curve and then try to mirror it; also not possible.

Please, tell me which version do you use?

I think you should create a bug report.

Latest version. And how do I make a bug report?
