Why do Tshark gives two data_rate?

Hi, Using "tshark -2 -r Dump2.pcapng -T fields -e wlan_radio.data_rate" on a OTA dump ( https://remy.grunblatt.org/Dump2.pcapng ), I get values such as "6.5,6.5" or "526.5,526.5".

From the documentation ( https://www.wireshark.org/docs/dfref/w/wlan_radio.html ), the values are supposed to be Floating point (single-precision). Is there a problem with the pcap? Or is that a problem with tshark?
