I have random stray points on my drawing. Anyone know why?

Hello Forum,

Can anyone tell me why I am getting random stray points on this drawing? It happens when I convert entities on the end of the weldment.

It started when I added a block, converted the entity, and then used autodefine. It decided to use the origin for the datum point...

I also cannot remove the centre cross for the landing plane. I did a drawing two days ago with almost the same setup, but on that one there are not centre marks...

I can't seem to find out what has changed, and where the changes have happened

I think it is similar to this question: , but there is no answer to this...

Any help?
