I am having this problem as well, setting stand = TRUE causes this error about the replacement having the wrong number of rows

It seems that using std.lv = T adds an extra row to the ParTable chunk of the lavaan model object. I don't know why it does this, but it makes it not give the same answer. I would suggest that you try omitting the stand=T if you're going to use std.lv = T and see if that gives you what you want. If you're not putting coefs on the plot it should definitely work at the very least.
