Am I using an Alpha? 9.1.002

I was having trouble so I went on to my system and went to LibreElec settings, updates

I was in the LibreELEC-9.0 "train" (chain?) of builds.

Available versions was 9.1.001 / 9.1.002 etc

So I grabbed the latest.

Is this an alpha? How can I avoid this in future? Should all beta and alpha be called

9.1.002a or something in future?

Or chaing the train to

"LibreELEC-10.0 - testing" ?

Ok it seems the descriptions need to be fixed up to avoid this going forward.
