I have tested it on my end and was able to replicate the issue, it seems to be only when enabling the Auto Fill option, I will report it to our second level so one of our developers will take a look to the issue and you will be notified when it is fixed.
Thanks for letting us know. It should be working as intended now. Could you please try it and let us know if you have any issues?
