Vintage Warwick frets

[Mugr]

So I just picked up a used Warwick Fortress One from 1995. After taking the strings off and cleaning the fretboard, I noticed at least one of the frets is lifting a bit. Is this major? Does it ruin the bass?

It needs to be re-seated. If you press it down does it pop up again?

Yes it does
