LUpdateOPtions does not remembers its value once MSVS is closed.

If a value has been set to LUpdateOptions in Qt Option -> Qt Default Settings of MSVS Addin and OK is pressed. This value is no longer remain saved in LUpdateOptions when you restart the MSVS rather this value gets stored in LReleaseOptions:

Step to reproduce:
Open Qt Option and Qt Default settins
change LUpdateOptions to -no-obsolete and press OK
Close MSVS and restart
open Qt Option and Qt Default settings experience LUpdateOptions is empty and
LReleaseOptions has value -no-obsolete
