Slow battery charging after lollipop

Hello, my LG G PRO 2 is showing the message -> "Charging slowly with a charger/USB. Connect to a standard charger to charge faster." However, I'm using the original charger and charging it directly from the original AC Adapter.

My LG G PRO 2 Software version: D83820d-TWN-XX and I have already tried factory reset. What should I do? Downgrade or is there any other solution?

Thank you!
