Renaming Photos With Taken Date Limit

Hi everyone,
When I try to rename more that 20 or so .jpg files with the "date taken", AR will display the new name for about half of them correctly and then the new name of the others with 3 underscores plus the collision rule digit.
e.g., ___02

The "date taken" doesn't show in the AR window for these files when this happens. If I clear the list and add the files that didn't show the "date taken", the "date taken" now appears for those files and it displays the correct new name.

It's like there's a limit to how many can be renamed or some kind of cache that gets filled up. Sometimes I can add 50+files and it works fine, but most of the time I encounter the issue above.

Any help would be greatly appreciated. Thank you.
