Aircraft X was climbing out of around 24000 ft on the RNAV departure to his filed altitude of 28000 ft. When he checked on; I cleared him direct. The pilot requested to remain on their flight plan route and to stop climb at 26000 ft to burn gas. I hit previous route and after coordination entered his new final altitude of 26000 ft. When I hit previous route I received a UTM (Failed Transfer) message to the next Center sector. Several minutes later when the next sector took the handoff the route changed back to direct and the altitude reverted to 28000 ft. I coordinated with them to make sure the correct information was passed; but it was unnerving to have the aircraft's flight info change with no warning when the handoff was accepted.Whatever bug that is causing the UTM needs to get fixed. This happens fairly frequently; and while usually just an annoyance; this could be a real problem if the controller were busy and did not notice the UTM. Usually it is just the flight plan that is a little off; but in this case both route and altitude were passed inaccurately.
ZFW Center Controller reported that after handing off an aircraft to the next sector the aircraft's amended altitude and route reverted back to the original information.
