Force Sync for Windows?

I wonder that this should be a issue but my Windows 10 PC does not get/send updates if I change items.

For example: I do some editing on PC "A", I can see the changes on my iPhone but on PC "B" there is no change.
If I lock/unlock 1password on PC "B" the change was visible. It even helps to add a "dummy" note but this should not be a solution?

Why is this? Why does 1password not sync and why is there no "force sync" option available?
