Labeling Trope as Age Gap

I don’t know if this is just me but I feel as if you should not label your book an age gap romance if they are only 10 years apart, or say 20s-30s, 30s-40s! To me, true age gap is when one character is in their say 20s and the other is in their 40s to 50s - where it is plausible they could be the characters parent!

I am just getting really annoyed with every book saying it has an age gap trope when it really doesn’t. I am someone who doesn’t love age gap romances so I hate that I truly have to investigate every book on Kindle if it is one or not.

Also I’m currently in a mafia phase so I’m seeing this a ton!
