Hello. I am using the directory tool to grab all files that end with .xlsx in a folder. Here is what it looks like.

So in this folder there are multiple files, each with almost the same name except they are numbered differently at the start. For example,
1. File Worker January.xlsx
2. File Worker February.xlsx
...
12. File Worker December.xlsx
When I use the sort tool

These files that are NOT in the folder end up being included:

What does the ~$ mean? How can I remove them? My goal is to retrieve the most recent file added by number (so in this case 12) and then use that as my dynamic input file for my flow. I cannot do this as it gets the ~$12 file which cannot be read.
