Why do I see an App Version Code as 'Unknown' in Google Playstore Console?

Question

I have an Android App which is live in the Playstore and I was analysing the ratings for different version codes. I found something which doesn't actually make much sense to me. In the list of apps with version codes, there happens to be a version code labeled as Unknown Each and every app which I had released had proper version codes with it (or else the playstore itself won't allow me to publish). I am wondering from where this Unknown come from. If anyone else had faced the same issue and have an explanation for the same, please help me grasp an explanation.

Attaching the screenshot for further clarity.

Thanks in advance :)

Here is the quote form different thread:

I contacted Google Play about this a while ago and they finally answered and offered a likely explanation about why the "Unknown" version(s) are the worst rated: If a user uninstalls the app, and after that decides to rate it, then the version will appear as unknown because the system can't figure out what version exactly the rating is referring to since the app is no longer on the user's device. And the users who are most likley to uninstall AND rate the app are those who really disliked it, hence the low ratings.

But in my case Uknown version doesn't have the lowest rating. It has the average.
