Sheet order bug?

Hello,

I found a problem in DrafSight V1R3.1, I am using linux version. I normally have sheet/model tabs visible and I like to have certain order of sheets. When I hide model/sheet tabs, my sheets aren't in the right order under the drop-down "sheet" button.  I think sheets are sorted according to their creation time, not user specified order, under this button. Is this the intended behavior? I think the sheets should be sorted as user has chosen even when using this button.

I attached .dwg file and also a .png file showcasing this problem.
