What's with all the dimensions ???

Hi folks,

This has only been happening since my recent re-install of SW2016 SP3 after my complete computer crash about a month ago. Now, when I make a mirrored component SW by default displays what seems to be every dimension used to make that part. It never used to do this before! I have played around with certain 'hide/show' views and can't seem to get rid of them and the current display state is a newly created one.

I've no doubt that there is something blindingly obvious that I'm missing but I can't figure it out. I've looked through previous posts but the closest I found was about double dimensions and didn't help!

Part is attached.

Go ahead............. show me how foolish I am...................

Dave.
