The S94 tag needs to use two fields per parameter, the parameter itself, as well as the value.  For example:

Syntax:
[[S94:region:region:numLinks:number:issue:issueID:states:states:taken:taken:desc:desc:sortBy:sortBy:link:linkType:listStyle:listType]]

Example:
[[S94:region:allalerts:numLinks:999999:issue:-1:states:allstates:taken:show:desc:description:sortBy:priority:link:title:listStyle:plain]]

So region:region becomes
region:allalerts

And numLinks:number becomes
numLinks:999999

With both parts filled in the S-tag should then populate properly.
