Okay MWillems beat me to one of my points. Turn off the "move all files" flag. That is your main issue.
I use the JTV recording format which always creates its own directory for each recording, so I don't see these sort of problems. However...
If you recording folder (H:\Temp-Recordings) is not watched, how do you use MC's "Rename, Move & Copy" tool to move the files? MC has to know about them to move them, so it needs to have imported them. Also, you are talking about XML Sidecar and JPG files in the temp recording folder, which then got moved to the Columbo folder in this case, then the recordings have definitely been imported, and metadata collected for them.
So I don't understand your workflow. Do you manually import the (H:\Temp-Recordings) folder before doing the moves? If so, do you wait long enough for the import to do everything, including collecting metadata? Otherwise you may interrupt the collection process.
I would just have MC watching the (H:\Temp-Recordings) folder, and then move them later. If you want to keep them separate then perhaps you should modify your views to exclude that directory, or use an approval process such as described
here by BLGentry, with the variation suggested by Glynor.
