The 2-digit and 4-digit terms for loco addresses are actually incorrect and misleading. These terms are never used in the the NMRA DCC Standards specifications.
That is why we have moved away from this incorrect terminology in JMRI and now use "Short" and "Long" terminology, both of which terms are used by the NMRA DCC Standards. (The NMRA also uses the terms "Primary" and "Extended" in some places).

I ran across something similar to this regarding 2 or 4 digit. In hex, 151

trying to call my train engine a 4 digit (more than 2 digit) and the
decoder wouldn't take right. I couldn't get a read back on the decoder.
Made it a 2 digit number instead of 4 and it took. Maybe that is your
problem? If it isn't that, Sorry....
