Any listings I now have with a KP number I can't book a courier from sold 'Next Steps' section anymore? I have messaged TM about it.

I'm finding all the new changes with TM at the moment super frustrating. - It looks like there are more than 25 listings per page now. And subsequently went over my 'allocated' number of listings. - I can't end some of listings early now. - TM is very slow to respond to questions and issues relating to the new updates. I'm really unhappy with the new changes.
