Comment Box Not Appearing

Could someone please look at my site and help me out with this issue I’m having. Okay if you go to this page

https://www.ntsshow.com/wordpress/2007/08/27/floyd-factor/

at the bottom the comment box appears like it should. If you look at the sidebar on the right and in the dropdown under OTHER ARTIST if you click on Floyd Factor there the page changes to

https://www.ntsshow.com/wordpress/category/clr/floyd-factor/

and the comment box disappears. I need to have the functionality where when users use the dropdown box to switch between artist the comment box is there. I have searched the forums and I can’t seem to find the answer. And help is GREATLY appreciated.
