Problem with CF2018 MultiSelect checkboxes and select passing an array rather than a list

I ran into a problem when applying the 11th update for CF2018 as the drive ran out of space, which corrupted the files and ended up having to uninstall and re-install on a separate drive in order to resolve the issue; however, now I am dealing with an odd quirk in that when a form with multiple checkboxes or multiple selections from a select lists is submitted -- I receive the variable as an array rather than a list, which causes issues when I attempt to pass that variable into a query via cfqueryparam.

Is there an option that can be adjusted to control this behavior?   My code has not changed and now gives an error about a complex type.   I would prefer to have the items submitted as a list or string, as otherwise, I have to go into my code in all these places to test if it's an array and then call ArrayTolist, which was never needed before the reinstall.
