Docked Toolbars Moving Around

I have a custom toolbar that I like to dock at the top of my screen, on the second row of toolbars. I like to have it on the second row because the first button is open, and then it sits just below the File button on the Standard toolbar. 

When I change files, this toolbar jumps up to the first line and toolbars from the first line move down to the second. 

I think this has something to do with the resolution width of my screen. At work, I use a 1920x1080 monitor and dont have this happening. At home, my main is a 2560x1440 and it keeps happening. I log into a virtual machine from both home and work, so its the exact same setup each time, just a different resolution.

I have had this issue before, which was the reason for creating my custom toolbar in the first place. My only thought is to add a few more buttons to the bar to make it wider so that it cant jump up to the first line.

Thanks
