REX firmware 1.03- please check UDI and PWM pos signals ,if failsafe is enabled

Hello
1. Using PWM pos signals (CPPM) with follwing settings in the mainsetting sector:
Failsafe enabled, output peride 24, PPM8, computed,
Out put pin settings: y1-ch1, servo, failsafe enabled, pos -100%
Y3. PPM 8 , PWM pos,

the receiver shows following behave: Servo direct connected to ch1 at the receicer goes, if I switch off the transmitter, to a perdefinded fail safe position ( -100%)
Using the PWM pos signal together with a gyro, the connected servo takes the hold position, switching the transmitter to off. That means the signal of PWM pos and content of the signal, direct on the REX receiver has a different content. Using a R3L receiver with firmware 3.24 all things are going well.

2. Using UDI 12 with following mainsettings: failsafe enabled, output peride 10, UDI , direct
Out put pin settings : same as before with the exception UDI instead CPPM

Here occurrs following behave: If I switch on the receiver , while the transmitter is switched off,
the UDI signal content is this case is high (2200) at all channels. I expected to find no signal.
Direct at the output pins on the receicer I could not detect a signal.
Here I m not sure, is the problems comes from my gyro equipment.using computed as setting in the mainsetting sector, all is o.k.
But using firmware version 1.02 all my concerns are over. Therefore at the moment I' m using Version 1.02.

Please have a look to the firmware , perhaps I'm wrong.
