I figured out what was causing it and fixed it. We locked it the default decimal amount of 50% and then showed the prompt to change the amount which then had no effect because the default amount was already locked in. It is fixed now and I tested it on the preview link, looks good to me. @ashachaf can you confirm that it is working as intended now?

@Velua can you polish this off by triggering the WETH balance to update once the withdraw is confirmed. Currently the site seems to needs a refresh to show the updated WETH balance.
