Check if the problem doesn't not simply come from a change in the sensor database. We have already seen this problem, like for instance #495. In case the sensor database value differs, please notify if the value in the latest release results in worse results.

There is also a bug in the release 2019.1 described here which creates problem when you have some images poorly connected. It is fixed for the next release (2019.2), in the meantime, if you have this issue you could use the previous release.
