Question on Phoenix 200 shift

I’m a bit mechanically challenged, I know just enough to be dangerous… anyways on my Phoenix 200 when I shift from R/N/F 2 things happen, and not all the time:
1. the N & R light are lit at the same time whether I am in N or R – doesn’t happen all the time, but better than 50%
2. when I shift from N to F or N to R I throttle, I get a clunk (engages the transmission after a second)… I have to feather the throttle to make the clutch engage, otherwise it will CLUNK into gear.

Question: do I just need to make an adjustment in my shift lever linkage?

note: I do notice that my rear tail light will flicker off and on when driving… not sure if that is tied into the issue, but may make me believe it could be an electrical issue?

any thoughts?
