Can't set the local port with UDP in M65

Good day everyone,
I am not able to set the local UDP port with my Quectel M65 module. I own a EC200U 4G module from Quectel as well and I have no problem setting the local UDP port with it, but M65 is giving me a headache.

These are the AT command sequences that I executed on my M65 module after I turned it on

**AT+QICSGP=1,""**
AT+QICSGP=1,""
OK
**AT+QILPORT="UDP",38080**
AT+QILPORT="UDP",38080
OK
**AT+QISERVER**
AT+QISERVER
OK

SERVER OK
**AT+QILPORT?**
AT+QILPORT?
TCP: 2020
UDP: 38080

OK
**AT+QIOPEN="UDP","172.X.Y.Z",30330**
AT+QIOPEN="UDP","172.X.Y.Z",30330
OK

CONNECT OK

However when I send something with the AT+QISEND command, on the receiving side I see that the source port is 49607 and not 38080 as I had set it with the AT+QILOCIP command. What am I doing incorrectly? I wasn’t able to change the local port no matter what I did

Thanks a lot
