Sounds like you have DVD titles that My Movies would classify as Box Sets. The UPC is for the Box Set container and the individual movies would be child titles within that box set. Typically if you add the Box Set UPC using My Movies for Windows you will get the box set itself and the associated child titles, IF the titles have all been contributed correctly to the database. Sometimes you will only get the Box Set container (the one with the UPC you are listing) as the child tiles have not been incorporated into the box set in the database yet.
Two things come to mind for Hallmark titles. In my experience with the My Movies database, Hallmark movies are somewhat obscure movies in the first place, they may not have even been added to the database yet. Major movie theater and subsequent DVD/Blu-ray releases are almost always found in the database, but made for TV movies from a US cable TV channel sometimes are not. Second, Box Sets of obscure movies are even less likely to have been contributed to the database. I have quite a few Hallmark or Lifetime channel movies in my collection and have had to add many of them to the database myself. You may have to add the movies yourself using the My Movies for Windows desktop program.

You may not get the specific child titles or box set containers you currently own, but you just might be able to find the single DVD version of the movies that are on your box sets. Can't guarantee all the movies have been added to the database, but I know of one on your list that is, as I contributed to it myself.
"Come Dance with Me": UPC 883476093536
They will not match the UPC codes you have, but at least they will be in your collection as placeholders until the database is updated with the box sets you own.
Keep in mind that many titles are contributed to the database by fellow users, so your box sets may take quite a while to be added/updated unless you do it yourself.
You can also "Report Missing Titles" and My Movies administrators will work on adding your titles, but probably only the Box Set container with the original UPC, not the child titles within. Contributing Box Sets with child titles requires having the physical discs to populate some of the data in the database.
