After the TS950SDX CPU reset I "lost" a 6 k Inrad filter

[EW1MM Gary]

Hello, everyone!
I modified my TS950SDX following WZ5Q info on his WEB Site and was absolutely happy,
but one day, I pressed the PTT foot switch to transmit, and the transceiver stopped working for both receive and transmit modes.
The first thing I did was reset the CPU.
This brought me to the factory settings.
I gradually returned everything to my settings now according to WZ5Q WEB Site.
Everything works well but the "SDX" "CAN'T SEE" the Inrad 6 k filter both in RX and TX modes.
The Inrad 4 kHz filter works very well both in RX and TX modes, but a 6 kHz INRAD filter doesn't show me anything.
It looks like I have no INRAD 6 k filter at all.
It doesn't even stop at the INRAD 6 k filter position when I switch over the 8.83 MHz filters.
It immediately jumps to 4 kHz INRAD filter.

My filters are in this order:
No Indication = 12Kc LC
6K Indication = 6Kc Crystal
2.7K Indication = 2.7K Ceramic
1.8K Indication = 6Kc INRAD – it can't be seen both in RX and TX modes!!!!
500 Indication = 4Kc INRAD

Before I did a CPU reset everything was working very well.
Please, give me any advice.
Thank you very much in advance.
With best regards,
Gary EW1MM
