Facing Developer Studio Multiple Tools window

What is exactly the problem?
Btw, you should move to vscode as developer studio is going to be end of life.

Check the tool bar in image…

you can still use it, right?

Yes i am using it…

Then what is the problem if you can use it?

See that image in my developer studio i have gating multiple Tool bar…

Maybe you can reinstall it.
In my opinion, if it can compile then it is ok to me
