I suspect it comes down to an oversight by whoever wrote the original database specification - at the time the game didn't "need" (as it wasn't displayed anywhere) to store stats of players after they left a club, so the database developer didn't build a table to store those stats. It's likely that they had tables which stored stats for each team's current players, plus tables which retained match records for the current season
Once Nordeus decided they wanted to store more history they got those tables built, but if the original results weren't stored anywhere it's impossible to re-build them retrospectively. So I'm assuming their player history datatables started storing goals etc. in February.
Sadly (I'm a data analyst by profession) an inability to fully predict the future needs when building databases is pretty common, even in modern times with big data storage capacity.
