OpenCV train cascade giving error "“Train dataset for temp stage can not be filled.”

so I've searched this online and this is a pretty common error but I've tried the given solutions to no avail. My cmd log is:

and my negativedata.txt file has 76 lines of info in the form:

Please can someone help me pinpoint the issue because I'm still not sure why I'm getting this error. I'm doing this on a windows system. Thank you.

Solution

Found out the issue, apparently the bg file shouldn't contain constraints so now my file is in the form

and it outputted my xml file fine; albeit taking a bit of time. Lol I can't believe it was something so simple holding me back.
