Calc has duplicate tabs at the top, no file name

I just installed ubuntu 16.04 and upgraded to LO

Now it has two sets of tabs across the top. As the file is being called up, for a second the file name appears, and I wish it would stay there.

What can I do to get the file name stay up there with only one set of tabs? FYI this also happens with Writer.

See here…it’s a bug.
