Need some help with Diminsions and Placement

As can be seen in the Image, this ruler is suppose to be 1" x 5" and the Box is 1"x 5".
The box was made in LB and is 5" to the grid and in the Dimension Boxes.
The Ruler was made with Vector Ruler Generator.
I know about the DPI settings and Use Illustrator for my own SVG designs.
Its set to 72 DPI accordingly and the Ruler SVG is 72 as well.
I’ve used VRG to calibrate my Axis before, in Centimeters but a older version of Lightburn and it was spot on.
This issue I noticed the bounding box is a problem, I had not noticed prior because I was was only after the increments.
The bounding box is significantly larger on the ruler than the Box.
To get them lined up within reason, and again the Box is 1"x5" and set with front left X-0,Y-0 but the Ruler has to be 1.0022" x 5.1119" and X-0 and Y–0.0468.
Its within reason but still not 100%

I also have had issues with size and position being arbitrarily changed.
Which is very frustrating to say the least.
Also ever once in a while LB positions thing on the negative, for instance I position/place work or template at 0/0, but LB sets position to -0/-0 and will not set the proper position.
I also have noticed weird behavior when switching between mm and inch on occasion.
This is been multible versions, I upgraded to most recent today so some of these issue may no longer be a problem. Time will tell.

But it be nice to not have to deal with this bounding box.

Little update it seems to maybe be related to the Inch setting as I just imported a Centimeter ruler and its on par.
No issues with bounding box or dimensions.
