Using ringtones as text tones

Since I downloaded the new iOS, iOS 17, my iPhone won’t allow me to use my ringtones as text tones. They’re in my ringtones list, but when I click the download ringtones from iTunes in my text tones, they don’t show up. I’ve even purchased new ones through the prompt that leads you from the text tones menu to the tones store, but still nothing. I just factory reset my phone as well, and still nothing. I’ve even tried to go through my contacts to assign text tones to that contact and it only gives me the general list, without my purchased ringtones.Please let me know if I’m just not doing something correctly, and what I can do to get the use I intended from my ringtones. Thank you!!!!
