Hi Jackie,
What I'd advise you to do, is to create a Screaming Frog Crawl so you can compare the two crawl data. If both show missing meta descriptions on the same pages, then there might be something on your side.
It is always good to double-check the information you are provided. So you are sure that the issue isn't a bug.
Gr., Keszi
P.S. I made a quick crawl with Screaming Frog on the first domain: sundancevacationsblog.com and found quite a big number of Missing Meta Titles.
