Database folder

I have my whatsapp databases folder. Inside it I have mstgstore.db.crypt14 file plus other db.crypt14 files named with the date that where made (example: 24-10-2021.db.crypt14). The issue is that there is some data missing. So it goes from 24-10, then 23-10 and then 21-10 an then 19-10 and so on. Some times there'ss even 2 days in a row missing. Does anyone knows how come that?
