Doubt about signing up for ICPC

My name is Aditya Kumar Singh but in ICPC signup page both first name and last name aren’t accepting space. So what should I do?

It will not accept if you include space in the input fields. Shorten the inputs and remove the spaces. Even I had to compromise on this.

Do that mean I need to write Aditya in the first name and KumarSingh in last name? And are you sure about that? Would there be any problem if I do so?

Are you using this for Credit Transfer?
If yes, then consider asking your coach about this.
It’s fine for me to shorten my name.
