Like this one?
I like white phal with red/purple center and lip.
Anyways, I dropped one pot of large phal yesterday and lucky only one leaf got a big scar.
I also have broken off leaf, old and new.
It causes no harm at all. The left over portions will grow out a little further and even if that's not the case, it will grow new leaves when in the right season to do so.
Yours just finished flowering, so most likely it will grow some leaves before spiking as long as it is kept warm enough.
Don't worry too much.
