Likes not showing in notification bar

I have a post rn that’s doing really well and getting like 500 likes per couple minutes, in the morning it would show me the exact likes I would get in that bar in the picture but now even when I get say 800 likes it only says like 5 or 6 likes just like in the pic above. Is this a glitch? Or does someone have a fix to this. Ik it’s something stupid but I liked seeing my exact likes instead of just 4 or 5 when in reality it’s 800+
