BME280 GYBMEP incorrect sensor readings

Hi,
I am trying to read sensor data from BME280 GYBMEP connected to ESP8266 (MOD-WIFI-ESP8266-DEV by Olimex) via I2C. There is also APDS-9960 light sensor connected in parallel.
Readings from BME280 make no sense at all (see below). Is it some kind of calibration issue or a faulty sensor?
SDK:2.2.1(cfd48f3)/Core:2.4.1/lwIP:2.0.3(STABLE-2_0_3_RELEASE/glue:arduino-2.4.1)
APDS-9960 initialization complete
Light sensor is now running

Ok, I've found an issue. It's different I2C address in my case - 0x76
