Secondary Standalone Toolbar is changing monitors by itself

I have a similar issue. My company recently migrated me from my Win 7 machine with dual monitors to a Win 10 machine with dual monitors. I have TLB on the primary monitor within the Win 10 taskbar and yesterday I created a standalone TLB at the upper right of my second monitor. This was working fine for the entire day--perfect. I logged off at the end of the day and when I came in this morning and logged on, the standalone TLB was in the upper right of BOTH the primary and secondary displays (the embedded TLB is still on the primary taskbar). I have not been able to figure out how to get rid of the extra standalone TLB on the primary display just keeping the one on the secondary. I guess I can live with the extra standalone but there must be an answer???
