uploading firmware - banner shows confusing message "applying firmware"

Applying in this context means, it will be applied to the second slot. 
There is an follow up banner, which means "Reboot now". 

I understand that - nevertheless you may admit at the first look "applying" is confusing and may be misinterpreted.

What would be a better banner message? 

(By the way: i am not a fan of the Upload only process, i am always upload / boot at the same time, when the downtime is applicable).

well "uploading" or "uploading to second slot"
since I upload only, then reboot both nodes rolling, then upgrade, upgrades are running without issues.
