### Steps to reproduce

1. In `Internal two way sync`, tap the 3 dot menu
2. See `Disable for all folders`, that implies I can enable it again
3. If I tap it, it actually deletes all folders

### Expected behaviour

Delete is fine, but to word as `Disable`, that is quite misleading

### Actual behaviour

It irreversibly delete the all the 2 way syncs
