Visual glitch when selecting gates

Pics included below. Issue spotted on PRG and BRI and is replicable on my device at least. You can tey replicsting by doing the following
1.Have empty cargo and pax gates(of same size)
2. Select plane and from the map tap on a pax gate square.
3. Tap anywhere else on the map to deselect a gate.
4. You should see cargo gates also light up.

Selecting them does nothing you cant land the plane, as said its just a visual bug
