I have used librecad off and on for a few years, mainly to draft plans for my house as it stands, and I have a new task to draw a bracket for a tractor and have started adding dimensions for location of holes etc.
When I zoomed out a few steps  I noticed a very large square box from the origin to the lower left corner of my drawing.  I have added many dimensions and now I have many large boxes too!
Drawing zoomed out to extents to show the large boxes

in closer still showing  the large boxes

one more step and they disappear

I am using version 2.2.0 rc1 91 .....
here is my drawing
MF_65_Weight_Frame_v1.dxf]

I have also been editing the properties of the dimensions to adjust the text - not all but most. I have also relocated the text from the default location for most dimensions.

I have turned off most layers leaving the dimensions layers so it appears that the boxes are linked with the dimensions I am using - just horizontal and vertical dimensions.

I cannot select the large boxes to delete them - why do they occur and how can I delete them ?
