GG, when you raised that saddle, did you make a note of how many turns you made?
TBH, messing about with saddle height can cause more problems than it solves. Saddle heights are set to compliment the radius of the fingerboard and often don’t need touching unless string guages have been changed. As Lee says, you can check the fret-dressing possibility by looking along the neck.
Before I type a lot of schtoof, can you provide some info? Useful info includes:
Make/model of guitar. Is it a copy of the usual suspects (Fender, Gibson etc)?
Has this been a prob since owning, or have you changed something, like the strings?
Is it just the bass E string affected at the 12th, or are other strings affected here?
Do you see obvious lifting of the fret anywhere, on either side?
Given a choice, would you prefer a slightly thicker E or a bit of work on the instrument?
So far, I suspect that the low E string is too narrow a gauge for the nut. There are other possibles, so the more info the better.
