Unable to create a copy of a folder

[gtm]

When I tried to copy a folder it complains
that another folder of the same name exists.
It should instead make a copy just as windows explore does.

E.g

MyFolder - Copy

[admin]

All fine here. What did you do exactly?

Same for me...no issue...when I do File>Duplicate>Copy here, I get "Copy of test" from "test"...not sure what gtm is doing.
