Can’t find Products list on the Export File

I have an issue that has come up I need help with

I downloaded the product export to start the process of updating my inventory and I noticed an issue.
on some of the Variations Name it supposed to be the [product – Size] but some are only coming up as [ – size] missing the product name.
On these same ones there is no SKU for some reason.
I can’t find it by product name or SKU but I do have an “ID” number but still can’t seem to find it.
Can you help on how I can search it on my site to find it an update it

One product I have which are boots only has 32 to choose from and I looked at every one and they are all updated right. But on the list of items with no SKU or Name there are some on there that sow the size under the name but nothing else.
