Hyperlink wont show up??

Hi all

Just noticed something very strange. I went to update the page above, i added the previous webinar (from the other day) to it. When i add a new webinar, i link the title to the new corresponding post i just made for that new webinar, with a hyperlink.

The title is all there and showing on the admin side, but when i click “publish” the page isnt showing the title. If i remove the hyperlink it shows again, but as soon as i make it a link it wont show when published.

Its only affecting this new post, as you can see, all the old posts are still showing with their titles hyperlinked so whats going off??

Ive deactivated all plugins, updated everything, i cant see why its doing this. Can anyone help?

I did notice that as soon as i published the post, instead of using the title as a permalink, the website used some random number instead, even though id not altered any permalink settings. I deleted the post and re did it and the system used the title as a permalink properly but i wonder if thats something to do with it.

thanks
