Grinding MT 1st gear only

I believe I've used RoyalPurple Synchromax in my transmission after trying Castrol syntec 75W90 and was pretty bad for the transmission.

RoyalPurple was not better, and obviously the wrong type of oil. Drove it a while, then change it to Amsoil GL4.

Transmission has been better since, but I still get the occasional grind shifting into 1st while not 100% stopped. But I'm still grinding shifting from 3rd to 5th when reving high.
