Marriage visa ,ihs application

Hi everyone, I made a bit of silly mistake when filling out the ihs application for my wife who is coming to the u.k.

I entered the wrong title ,I put Miss instead of Mrs , can we manually correct this with a pen,I have already paid the fee and was hoping this could simply be corrected manually with a pen before she attends the appointment?

Any help will be much appreciated.

It is a minor error and not a deal breaker for a refusla.
