editing Hex Numbers fail in some cases [message #1814939]

Hello,

I tested my grammar with some hex numbers and the editor doesn't complain with 0x00 0x06 to 0xff but with 0x01 to 0x05.
When i reduce it to a simple grammar it works but in the complete grammar not.
I get with EVAL CHANNEL 0x05
mismatched input '0x05' expecting RULE_BIT8HEX
That's weard.
Here's the download link for the complete grammar.

I tried with 32 Bit Hex Values and it works, so far i have the error just with 8Bit.
I use Eclipse Photon.

Looks like a conflict with the DACNUMBER rule. You reserved the tokens 0x01 to 0x05 there.
