I have the same problem since the last two updates (current version: 16.1.5.4270)

Well, it works here with the version you mention:

My apologies, I did not formulate the question correctly. What I mean is: when we open Studio, all projects show (In Progress and Completed), even when filtered for "In Progress". I'm adding a screenshot to show the problem.

Indeed, after Studio restart the filter seems not to be applied. Only if you change the filtering condition the settings are applied correctly. So we still have this bug.

OTOH, what is the reason for keeping completed projects in the list? In my case all completed projects are removed from the list. This way the list is short and tidy...

It's easier to go back to them if necessary, so I usually leave them in the list for some time. And everything should work correectly anyway - after all, we are paying for the software, right?
