RACE Activity 5.10

Hello, everything till 5.10 worked OK. After upgrading to 5.10 I have problem with race activity.
If I select activity (for ex. RUN, then RACE, history and select the date at which I done it before), wait for GPS signal and start. The field on the race screen (moving two people) are empty, doesnt show time AHEAD or BEHIND, EST finished time, EST, ETA and EPE are free, no numbers. With the SW 4.10 worked perfectly. GPS 1 s or smart.
Anyone has the same opinion? What is wrong?
