Will UW accept the ACT score that I'm not receiving until after the college app deadline?

So, I took the ACT on October 28th and have not yet received my score. As a result, I couldn’t include it in the University of Washington app because today is the deadline for it. I’m concerned that the school will be confused if they receive the score report for a score not listed on my application. There’s a space to mark if you plan on taking the test in the future, but there’s not one for if you already took the ACT but have not received your score, so there is no sign on my app that I took the October 28th ACT at all. On the website, it says you just need to send scores before December 31st, but is it ok if one of the scores you send isn’t mentioned on the application? Thank you!

UW accepts sat and act scores up until Dec. 31st
