Major stores missing in PDI convenience store data?

Hello,

I am curious to know if the PDI convenience store data specifically has 7 Eleven, Buc'ees, and Pilot (Flying J) in the dataset. These are 3 of the major players in the convenience store space, but I can't seem to find them in the data. I went onto PDI's website and they boast that these three stores use PDI, but I don't see them anywhere in the data. Additionally, the Dewey website states that this data covers "nearly 80% of the market" which I would imagine this includes these 3 stores. I am looking specifically in the STORES_INFORMATION table and these are not listed. Am I missing something?
