Read and understood your history of having a whole after freezing the wart.
This means that the killed tissue due to freezing have fallen off and thus created the whole.
Do not worry, if you have done the procedure well, there will be complete healing.
Yet on the safer side, consult your Doctor, preferably a Dermatologist for clinical evaluation if the healing is delayed.
I hope this answer helps you.
