Bug when editing existing payments

Issue: When I try to edit an existing payment amount and click the save button the app keeps crashing. I tried this on two separate phones and this issue is reproducible. I am currently unable to find a work around for this.

Details to reproduce: Happens every time on two separate phones.
OS: iOS 18.3.1.
Device: iPhone 16 Pro Max and iPhone 12.
App Version: 6.15.0

Screenshots: I can send videos of this if needed but a screenshot won’t display the issue.
