Grey box wth axis

I have this strange grey box with an axis in the corner and i’m not sure how to get rid of this. I am unable to click or select it. Any suggestions?

Appears when you create a component and set “Glue to”:

I didn’t make a component but I did insert a sink from SU Podium browser and had to unglue it so I could move along the blue axis. I decided that I didn’t want this anymore and deleted it but I am still left with this.

just tried to make it as a component and see the options and it deleted! thank you very much.
