Problem with multiple characteristic with same/similar UUID

[tomasz-kos]

I'm using Silicon Labs Thunderboard Sense - to evaluate development of BLE device and using BLE with OpenHab.
Default application provide a lot of senor characteristic some with standard UUID some with non-standard.
I started with parsing strategy "Recognised Only"
First problem I got was error because of the duplicate characteristic with this same UUID - for service Automation IO(0x1815) in app they ware 2 characteristic Digital(0x2A56). According bluetooth standard it is correct - 2 android application correctly handle that situation.
So I changed firmware and removed 1 characteristic - from that point rest of standard UUID was discovered and parameters as temperature, humidity, pressure were displayed correctly.
But I think multiple characteristic with same UUID should be correctly handled.

So my next step was to try see binary data for non-standard characteristic - I switched parsing strategy to "Recognised + System + .. + unrecognised as binary".
And I got again problem with duplicating channels.

None of previously working characteristic is displayed.
Learned from past I checked if I don't have multiple same 128 bits UUID, but no.
There are 4 128-bit UUIDs with "F598DBC5" - but they are different.

Could you check where is a problem?
I'm not using custom GATT files.

My setup OH2.4, BlueZ 5.47, Binding 1.1.6 tinyb 1.1.3
