Not able to type name and A-number in 'Additional Information' section

I am currently filing my I-130 and I-130A petition. While filing I-130A I need to add additional information in part 7.

According to USCIS instruction, you are supposed to provide your name and A number in Part#7 'Additional Information' section. However, the editor does not allow me to type anything in the name box (1.a - 2). I have tried it out with multiple editors and all of them behave the same way.

Can someone please let me know what can be done in this case? Is is alright to print the form and hand write the information. Or am I missing something.
