UC Periodic Redeclaration help

Hey everyone just a quick question,

I was sent a "Check your Claim Details" form over the UC portal online as part of the new rollout for periodic redeclarations, but I think I messed up on one of the questions as I'm not sure what's being asked

On the final question about savings it listed the amount in my account when I made my claim and asked if these details were correct, I clicked "no" as there has been an increase in my savings of about £150, but the next page it took me to was a "Report a Change in Your Circumstances" page

From my understanding with UC it doesn't warrant a full report of a 'Change in Circumstance' until savings are over 6k, but mine are not - I backed out of the page but it sent a Journal message saying my report for a change in circumstance was cancelled so now I'm not sure what to do, I can't find an option to amend anything, do I need to submit a manual change for this small difference? I had assumed the redeclaration form would just let me enter the new amount
