Occasionally it happens that material at the end of the first column is not typeset.

It occurs haphazardly in a large (more than 300) series of items. Depending on the length of the first columns material (I introduced extra space with \crlf, \blank, \blank[dimension]) other items exhibit the effect.

Because of this haphazard character, the large data set and the fact that I could not isolate it in a few items, I regrettably do not have a minimal example. Thus I can only signal it here, in case others encounter it too. Or in case the person maintaining this code happens to spot the problem from the observation alone.
