some same cases data is not important, and replicate them from primary to secondary will waste servers performance. Is there any ways to config?

MongoDB Secondary server shows higher record count that primary

We have a 3 server MongoDB cluster where there is one Primary, one secondary and one hidden. In one of our collections data gets only inserted by the front end APP and cannot be deleted. I am seeing a strange behavior - when I run count query on this collection (from shell) I always see secondary's count 1-2 more than the count on Primary.

Is this possible or is there some mismatch in my configuration?

Please advise if a NodeJS app should keep its historical data in a separate MongoDB databases?

Please advise if a NodeJS app should keep its historical data in a separate MongoDB databases instead of keeping them together with the application data?
For instance, 'transactions' collection and 'transactionhistories' collection, will it be better to store in different databases or single database for the same NodeJS app? Thanks!
