Package officer does not write flextable to word when flextable function delete_rows is used

Question

I am using most up to date version of packages (flextable 0.9.4 and officer 0.6.3). It exports table perfectly when delete_rows function is not used and gives this error message when it is used: Error in $<-.data.frame(*tmp*, "vertical.align", value = c("center", : replacement has 132 rows, data has 102

Is there any way to fix this?

I tried to run it with and without delete_rows function.
