Opening a new project opens inside of old project

[timbishop4000]

Recently updated to newest Premiere.  Sometimes I will open a project while a current project is already open.  I just go to FILE: OPEN PROJECT.  There has never been any issue and the new project opens up and the old project goes away.

Now, when I open a new project, the old project stays. So I'm seeing all of the files, etc. 

So I have to completely close Premiere, then open it up and open the new file.

Not a big deal, just curious if this is a bug or what.

Sorry I can't contribute with an answer, so maybe I can contribute with one more vote on this matter? I do too find this modality really annoying and confusing. What's the point of saving each project and giving it a specific name if at the end you have a kind of Master session full of tabs and full of unnecesary footage from a different project. 

Starting on a fresh canvas was much more cleaner to my mind. Any way, I hope Adobe takes us in consideration.
