Maybe it's a little bit late but, i had the same issues. What I did was to add a "delay" between each dialogue. Simply use the "Wait" function, I used a value of 10 and the problem was gone.
Hope it helps!
Might start playing some rpg maker games and uploading the games on youtube. Realistically they're not going to be for views. Just to give anyone some feedback on any games they're working on. So if you'd like me to play and review your game just reply them down here. And I'll upload them on Rpg4MGames.
