Hard shifting LJ71

[LS1FJ40]

I've put about 1100km on my LJ71 since I got it. The master slave cylinder was replaced immediately before I got it. It shifted fine when I got it. The clutch seems to be softer coinciding with having a hard time shifting. Especially down shifting. Is it air in the hydraulic line? Or where should I start?

Thanks.

So, I now can't get into first gear. My buddy thinks it is probably the synchro. Does this sound right?

Bled the slave. Air in the lines. It should've worked it's way out by now. So, I'll watch it and see if it happens again. At which point the master might need to be replaced. Again? Shifts smooth as butter now.
