I am using

redirect.toSavedSearchResult({id: <mysearchid>})

to redirect upon submit of a Suitelet (the suitelet also edits and saves the search before the redirect). For some reason, the results when they are displayed have duplicates of all the columns. If you go to edit the search, the columns are only there once. If I run the search from elsewhere (or edit it) it looks normal (one of each column), it's only when the results are displayed directly from the redirect.
