Honor Reset or False Report?

Like I said in a previous post, I barely say anything in-game. Had a long day at work and lag and an ally was frustrated with my playing and kept saying to report me. Then after the game I found my honor reset from 5 to last checkpoint before level 4.

Does the honor reset to a lower level once the new season starts or is this a false-positive by Riot bots? And for those of you saying I'm just complaining, I challenge Riot to provide chat logs for the game https://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2961827599/42034648?tab=overview.
