Having trouble with Rename

I have a rule and once it is matched, I copy a file to two new locations and then rename it with date and time as part of the file name.
Here is the actions taken:
Copy to folder (specified folder 1)
Rename with pattern: [name]--date modified][extension]
Copy to folder (specified folder 2)
Rename with pattern: [name]--[date modified][extension]
[date modified] contains this date and time pattern: 1999_12_31--01.30.59
The file gets copied to folder 1 and is renamed exactly as expected.
filename--2023_12_13--09.26.52.numbers
The file gets copied to folder 2 but is renamed incorrectly.
filename--2023_12_13--09.26.52--2023_12_13--09.26.52.numbers
The date pattern is repeated twice on the second rename.
Any assistance or ideas would be greatly appreciated.
