connection dependency

I am unable to locate the feature that allows an existing connection to remain connected when I disconnect from another one or it is disconnected due to internet connectivity reasons. I have two connections that I access simultaneously; however, if I disconnect one or the connection goes down due to the host's disconnection from the internet, the other goes down as well. Neither connection will re-connect. My JumpDesktop.exe task ends, and I have to run it again to open the app. I'm not sure how old this feature is (if there is one), but I have not had to adjust it until recently. I have had jump desktop for about 12 years now (installed on over 15 PCs, iOS devices, and iPAD OS devices) and have just started experiencing the problem. Thank you in advance for the help.

*Edited:

If I am connected via RDP, then locally signing in on one of the remote PCs will disconnect not only that PC but also the other remote PC. Manually disconnecting one remote from the client (clicking the X in the connection bar) will disconnect both it and the other remote.
