That's data aprs.fi has collected from the PHG (Power, Height, Gain)
extension which has appeared in the packet from your callsign-SSID.
You can update it by adjusting the PHG/PHGR field in the packet comment
text. The PHG extension is described in APRS101.PDF, and there is a
variant which also communicates the normal beacon rate of the station,
PHGR. There are PHG calculators online, for example this one:

You can delete the old PHG by transmitting a "PHG0" in the beginning of
the comment text.
