Warning: "you must also enter your income from Canadian and foreign sources" when amount is 0

Hi,

I have arrived in Canada (QC) in early January 2022 so I have indicated a date of entry into Canada. I was asked what my income from both Canadian and foreign sources was for the part of the year I was not in Canada, which is 0 in both cases.
I wrote that down in the form (even overriding the default that was already 0) and I get that warning:
You have indicated a date of entry into or departure from Canada. You must also enter your income from Canadian and foreign sources for the part of the year you were not a resident of Canada.

Can I just safely ignore it?

Thanks

Filing

Yes, if it is a warning and you are sure the information that you have entered is correct, then you can ignore it.
