I noticed that when i click "Affects Version" on this report page my server version (1.14.1.4) isn't there and there's only version 1.14.0.9 of the server, is this normal ?

Hello, i made a server on a dedicated Lenovo Thin Thinkcentre desktop PC and i'm experiencing a lot of server instabilities. Like:

1. Unresponsive redstone (Redstone doesn't update when i break the source and keeps being on)
2. My skin and my friend's skins are randomly swapping between us (They have my skin and i have theirs)
3. LOTS of lag, feels like network lag but my network is doing fine most of the time.

I made a server back in the days and it was way more stable, i don't know what happened but it's really bad right now. 

I remember having bug #2 when i was playing on a world hosted on my PC with a friend but our versions were mismatching.
