When looking at possible values of the logtype property of the watchlist API module on enwiki [1], the value "suppress" is included twice.
This list comes from the variable $wgLogTypes. The first "suppress" is default, the second seems to be added by ArticleFeedbackv5 [2].
I think $wgLogTypes should not contain duplicate values, so ArticleFeedbackv5 shouldn't be adding it.
