RT-73: CTCSS setting change itself after few transmitions

HI !

LAST Retevis/Ailunce FW

RT73: 109E.D4.EARSAB.007.F136-480

CPS: 9.1.170

I found that on Analog repeater with CTCSS set (here 103.5) for reception, after a few time/transmit the CTCSS setting change itself for other setting/or just became off (ex: the tone change for 62.5hz itself) And I can't ear anything until  I change it back to the right value or remove "signaling". I seen this on 2 repeaters I try until now.

Thanks !!

73!
