I've provided your feedback (including suggestion) to the DashPay devs on their Discord.
You did a nice job by sending my reports to the dash dev. Unfortunately I am not active in discord. But yeah I told about this in dash testnet feedback telegram group.
But I can not understand why I am facing the UI bug. Because some people sent some screenshots in tg where it is clearly showing without any bug.
Hope all will be ok in upcoming update
