I do indeed understand what your saying i've experienced it as well and concur it's very irritating.
What's even more irritating is i'm not able to do a thing about it...
The issue resides within how the data is sent to the server hence not updating to the correct item.
SOE will need to resolve the issue with how the data is updated.
An example on how to verify the issue is with the ThorUI before posting would be to use the default UI and see if it does the same thing you described here.
I'm 99% sure the issue is with the data not the UI but could be wrong...
I reserve the right to retract my statement due to ignorance...
