N/A and date by hand

[Evdokia]

Hello. I completed all the forms on the computer and printed them, but forgot to put N/A in blank boxes.
Is it okay to write them by hand?
Also, found this on cic site:
"You can fill out the form on your computer (recommended) or fill it out by hand.

• If you are filling it out on the computer: In the signature section, type your name and select the date using the date selection tool. Then, print out the form and sign in writing (provide your original handwritten signature) next to your name in the signature box. If you do not sign and date the form according to these instructions, it will not be accepted and will be returned to you.
• If you are filling the form out by hand: In the signature section, sign your name and complete the date legibly. If you do not sign and date the form, it will not be accepted and will be returned to you."

Wouldn't it be a problem if I write dates by hand on typed forms?

Thank you for your answers.
