Plugins Improperly close on replacement of Vst's with other Vst's

Windows 10. MS V4.5.1

In any score. load a vst in place of the instrument or FX and then when the interface is open for that plugin, swap it to another Vst. This will open the new vst and leave the old vst interface open which can pretty easily cause crashes. The crash itself may take a few times but the Vst interface should close on replacement. It seems it is properly programed when switching to Muse sounds and when selecting no effect. Order of operations should be, after button press, close current plugin with plugin interface. Then load new plugin in place. If you have any questions, please feel free to reach out and I will answer any question that I can. As this is a Global Issue, I am not posting a score.
