Bontrager Flare RT Battery level indicator

I've seen a few questions about the 1030plus and Flare RT combo - this one specifically relates to the battery indicator.

I've not had any issues with battery life or drain with the Flare RT - it's only a few months old. However whenever I connect it to the 1030 plus, the notification comes up to let me know that the battery is low. This is even after leaving the battery on charge overnight.

Has anyone else seen this issue? The battery level on the bontrager screen is always showing low so it's not an accurate representation of the life left in the unit.
