I-TASSER Exclude some templates from I-TASSER template library help

I would like to exclude some PDB proteins when modeling my transporter. I saw that there is an option for that on the I-TASSER webpage (option II). I wanted to exclude specific template proteins. I looked at the example on how to do that. I thought I did it correctly, but when I hit submit, the confirmation page did not show the excluded template proteins. I am assuming I uploaded the file in the wrong format. Can someone tell me how to do it correctly?

I opened Notepad and typed this into it:
4Q2L:A
4Q2M:A

Did I do something wrong? I saved it as a .text file.

If someone could help me, I would greatly appreciate it.

Thank you!
