Wrong name on citizenship application(after name change)

[backendcode]

Hello All,

I would appreciate if someone can give me advice and what should I do? So I did my name change (Split my name) before applying for citizenship.

In immigration, my name was
First name - blank
Last name (Family name) - First name, middle name and last name

So I legally change my name from service Ontario (Technically split my name)

After a name change,
First name - First name and middle name
Last name (Family name) - Last name

But, when I filled my application for citizenship. I mentioned that I want to change my name and attached my name change certificate but I noticed that by mistake,

I put a new name as
First name - first name
Last name - middle name and last name

but It supposes to be
First name - First name and middle name
Last name (Family name) - Last name

I applied in Feb 2018 and received my AOR and fingerprint request. Do you guys think I should update this typo mistake by web form or just wait until I get a request for a test and then mentioned to officer in the interview?

Thank you for reading this long and confusing post
