as far as i know, ILCD 2.0 is just an adaptation of the old ILCD 2011 by including newest CFs. ILCD 2.0 was not "officially" released by JRC, I think it was been required by Pré to Ecoinvent centre.
Indeed, OLCA methods 2.0.4 does not mention the ILCD 2.0, but only include the JRC 2011 version (for consicentcy reasons I suppose), which for Land Use it implement a different method.
I have just ingnored this ILCD 2.0. i'm not very confident about the revamped ILCD, i experenced something like yours too.
