I have experienced this when some other pattern has already processed and 
modified (or skipped) some of the occurrences. In PmWiki it might happen if 
the "when" parameter for Markup() is not correctly/optimally set.

Right, there is a problem with more than two (:markup:)[=code=] although it 
doesn't seem to happen on other places like BasicEditing where it appears 
more than twice. We'll have to investigate further to find out why and how to 
fix it, but I suspect something messes with the $KPV array.

Otherwise, using (:markup:)...(:markupend:) seems to work fine with more than 
two pagelists.

Thanks,
