Table.Buffer() function wrong data with no errors on refresh

Hello!
I encountered an interesting behavior, when I used Table.Buffer function in middle query, refresh all done without errors on OnPrem Server and on local PC also, but data is incorrect (like part of data is ommited), but after remove Table.Buffer step refresh lasts longer and data is correct (with a new portion). Could somebody explain what can be the issue?
