No problem, just that we are on the same page. I can see why you call that CLM.pdf, just needed to know the template used.
No, I also used the store button. I am not sure if the local OS settings have something to do with it, but they wouldn't have changed between TB versions. Right now I am at a different computer and the output for February is 199 kb here.
If I use the print button and then use a pdf printer (I have two here), I get one 141 and one 248 kb file, but with poor resolution, as you said.
A long story short: I cannot reproduce anything near the filesize you got there.
As for the date range: somehow that particular bit doesn't show in the picture you sent, but I guess if that is considerably more than a month, maybe accidentally, it would visibly affect file size. So honestly, I don't know...
