Definitely can't be having two of the same clue, mate.
Maybe have a look at how some others work.
Also quite simple.

Stranger things have happened. If it was that simple, it must have worked for you. (I wasn’t expecting it to have been allowed at all to be honest!

The double clues just add to the puzzle, they're not a problem. Unless you're lucky, I think you'd have to solve two lines in your head so you'd have enough moves to resolve the other two? And yet you can see the categories so easily! Ty DW

Two Timothys needs fixing. otherwise... fair enough

Frustrating grid, not very good.

The challenge shouldnt come from having to guess duplicates. Keep trying and keep on trucking.
