Insync plugin always gets deselected after a while

The insync finder plugin always gets disabled after a while - the context menu is then of course gone.
When I then enable the plugin again in the settings everything is working again.
what can I do to prevent the plugin from being deselected?
Maybe its because I have dropbox also installed (but disabled the finder plugin)?

what OS X / macOS version are you on? tagging our engineer @jimperio

I’m now using macos sierra but had that behaviour also on el capitan.
best, marcel
