Sent SATs But Forgot About ACT

I recently found out Stanford requires sending both the ACT and the SAT if you have taken both. I sent my SAT I and IIs, but I took the ACT for state testing purposes last year and did not send that. I plan on calling them tomorrow, but will this negatively affect my application? I fully intend to send my ACT tomorrow, but I don’t want it to look like I tried to hide or conceal something (which I absolutely didn’t). For what it’s worth, my ACT was slightly lower than my SAT at 34, but I don’t know if that matters.
