[Issue]: kodisync not sync right when library is updated

[comercy]

Please describe your bug

HI, I'm dealing with the problem that kodi sync is not working right. I installed jellyfin for kodi(angelblue05 -0.7.10+py3) in my android TV,and setup was ok,the library can be read correctly. I had Kodi Sync Queue(Kodi Sync Queue9.0.0.0) intalled. When I tried to update my library in jellyfin, kodi shows login without update library locally. I tried reset the library locally,and it works,new movie can be read.
