You might want to see this thread in which I predicted exactly what you are describing 
On the basis of what is known from this thread, and the thread I quoted above, I would conclude that the problem you experienced with Dropbox was down to using different paths on different Macs, and the problem you are experiencing with OneDrive is down to a changed path and/or non-persistent local files. The indexing mechanism in DT requires that paths are identical across devices and that files are persistent locally. If you don’t abide by those rules (through lack of awareness of the rules - your situation with Dropbox - or due to a change in the way your software works - most likely your problem with OneDrive) you’re going to run into problems.
