Narrative:

When selecting flaps 25 degrees from 20 degrees, the left indicator showed 20 degrees and the right indicator showed 25 degrees. Kept the flap handle at 25 degrees, performed a go around, followed ATC instructions to climb to 2000 ft on the localizer, then turned to heading 200 degrees and climbed to 5000 ft. The first officer did the QRH procedure, we came back and did an approach to runway 25L and landed without incident, approximately 20 mins later.
