Sounds more like a timing problem.
To get a better explanation, direct your question to Instructor Lisa McCormick or Caren Armstrong.. But here's my take on the problem!
Try just listening to a song and picking up the drumbeat or bass note. Dampen all the strings and strum with the beat.. When that feels comfortable and the sounds fit add two down strums. Then try two strums one up one down.
If things feel good start going with the chords..
Good luck and have fun..
