When exporting to database, CellProfiler's default is to truncate the column names if they are greater than 64 characters; it's not a just "truncate from the end" but drops vowels first, etc.
If you then want to use your created rules in FilterObjects, the rules which relate to truncated column names can't be matched to the "real" names; I feel like this used to work, but can't say 100% for certain.
