I have made a change sometime over the last few days and for the life of me cannot remember what I have done to cause this issue.
I only noticed it about 10 minutes ago, so going back over the last few days is really out of the question to reverse it etc
Basically there is a slight gap (where the arrow is) and I just need to close it down so the blue bar around the threads is then unbroken.
Thanks for any help that is forthcoming.
