[Closed] Rockshox Lyric R solo air problem

I decided to return my solo airs back to 160mm but i seem to have a problem with them . They felt stiff and would hardly move when stood up on the bike to set sag . I can force them down with body weight but they appear to judder back .
I have removed the lowers again and it seems my damper rod is sticking and when pull it down its not smooth , also if its all the way out it needs some force to push it back in .
Anyone else had this problem? I did not dismantle the damper side of things when adjusting the travel , i only adjusted the rebound (which doesn't feel great)
