What I think happens is that whenever you get a mention from someone like yourself @Rawrplus (position / admin panel access) then you get this PROFILE [1] and if you get it from a normal member it doesn't show. I wouldn't say it's glitchy but it's worth looking into and possibly it may be a wee change that needs to be done. 
@fragmeNt not true, I just got notification from u and ur forum profile is set as normal member
Yes,
@Rawrplus but unfortunately it doesn't work the other way round

Admin Panel Access member mentions a member = PROFILE [1]
A member mentions an Admin Panel Access member = PROFILE [1]
A member mentions a member = PROFILE
This is what I mean and if you could check that with like staff (Moderators / Head Admins) whether it's all true.
