File size for drawing DWG export has mysteriously increased

I'm not certain as to when, but sometime between now and this past February the file sizes for DWG exports of our SW drawings have grown 40 times. Yes, fourty times! We have been running 2024 sp 1.0 long before this started. Our drawing template files have not been modified since 05/2024. I have adjusted several system, dwg export, as well as, document options with little effect. Unchecking the document setting "store images for OLE object data in drawing file" had no real effect. I have been able to determine that our company logo (a sketch picture in our border template) may be the cause. When I edit the sheet format and delete the picture from the sketch the file size shrinks back down to normal. Another option is to export out as R12, which strips the logo picture out. What I don't understand is why this is the case. We have not changed any of our Solidworks options nor template files. Why is this occurring seemingly out of thin air? I have exported to dwg on three different machines and get the same result.

 

Anyone have this same issue suddenly appear?
