LPS25HB constant moving average

Good day,

For the LPS25HB pressure sensor I have an issue with a constant moving average.
I tempered with the FIFO mode register 0x2E and afterwards reset it back to 0x00. But I still have a moving average. Any idea what I could do to remove this?

register - value
0x20 → 0xC0 for active mode and 25 Hz
0x21 → 0x00 or 0x80 or 0x84. tried resetting the software and rebooting memory but no solution.

Thank you
