[Plugin: WPeMatico] Links from Article title

I’m using wpematico to create posts
I want to be able to click on the “Read more” tab to go to the post and then click on the Post title to go to the source
Sometimes it works sometimes it don’t
It seems that the theme makes a difference
What might cause this please?

TIA
