Reflect stops working when using bridge

In the attached file reflect stops working when using bridge. Just fooling around bridging things and I noticed this happened.

reflect the lower piece and try your bridge again. It works here-

Hi @theoutside
Yes that illustrates what I am saying reflect stops working and I have to reapply it again.
On the first piece I was able to bridge and reflect worked. Notice in the file reflect is still working until you bridge then it’s removed I know I can reflect that lower piece but it must be a bug if reflect is getting removed when you bridge.
Shouldn’t reflect work in this case without having to be reapplied notice that its still enabled on that main object?
Thanks for your quick reply,
