Kohya SS runs "repeat" number as a file name?

Hi, apologies if this post is missing any crucial information or is informal. I am very new to the coding game and am just testing everything out, and I've seemed to run into a problem i cant figure out.

I set the repeat number to any number and it seems to translate into a file name instead of running as an actual number.

"OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect"

For example, i set the Repeat value to 20 and it seems to create a path " \img/20_"C" "

'C:/Users/user/OneDrive/Documents/GitHub/kohya_ss\\img/20_"C:'

Please help me out, i genuinely have no idea as to what to do here?

No file or test is named in the report. Start by reproducing the Windows case with Repeat set to 20 and inspect where the path containing img/20_"C: is assembled. Done means the repeat value is treated as a number and the resulting path is valid on Windows.
