Upon configuring flaps from 25 to 30; Trailing Edge Flaps indicated a split and stopped tracking at 27 degrees. LE FLAPS TRANSIT light was also illuminated (amber light). A go-around was accomplished to enable time for non normal checklists to be run. LEADING EDGE FLAPS TRANSIT checklist was run which led us into TRAILING EDGE FLAPS DISAGREE checklist. Flaps were left at 27 degrees with flap handle at 25 setting. Vref15 +5 was the approach speed selected and an uneventful landing and taxi to the gate was accomplished.
On Final Approach to XXL in ZZZ and configuring from flaps 25 to flaps 30 at about 1;500 feet the trailing edge flap needle indicators displayed a split and the flaps stopped at approximately 27 degrees. The LE FLAP TRANSIT light was also illuminated. After taking a few seconds to realize what was happening and coming through approximately 1;000 ft the Captain called for a go around. I executed the go around; however upon attempting to retract the flaps we realized they were stuck at 27 degrees and would not retract at all. I continued to fly the plane and the Captain advised ATC and then ran the non-normal LEADING EDGE FLAP TRANSIT QRH followed by the TRAILING EDGE FLAP DISAGREE QRH. We received vectors from ATC and took our time setting up for a flaps 27 landing using the VREF15+5 knot wind additive. While being vectored back to the final approach course the Captain TEST and the FA's and made an announcement to the PAX. We landed and taxied to the gate uneventfully.
Flight Crew reported receiving a trailing edge flap asymmetry indication with a leading edge devices in transit light while on approach and elected to perform a go around in order to accomplish checklists and subsequently landed at destination airport.
