Is this a new glitch?

I was bobber fishing for the siniking lure, but I fished a Hylian Loach of 14 pounds, later I found the lure, later in the summer spring I fished one Loach of 20 pounds, I tried later to catch one of bigger size, I did (27 pounds) but it said to me that was smaller than my record, so I was WTF ?, I entered and checked the cage in wich the lure fishing fishes are, and I found a collosal-looking loach, really big!! I will post a pic or a video about it later.

So is this a glitch?

I think it's because it only keeps records based on where you fish, so if you fish in the fishing hole, they only record your biggest catch caught there, otherwise, i think the others are available in your menu screen, but im not sure

all this thing happened on the fishing hole
