Renaming Folder Truncates After "."

Hey all,
I'm attempting to rename a folder with the following pattern:
It works as expected, except when the <folder acted on> has a period (".") in the folder name. At that point, Hazel truncates the folder name to exclude the period and anything following. For example:
becomes:
I've attempted to use "Replace Text" to replace the period with another character (underscore), but that didn't work, and the truncating behavior continued. Is this a bug, or expected behavior with a workaround?
