We currently have Proclaim linked to a CCLI/Song Select account which we use to pull song lyrics into Proclaim. We then edit the song slides so that they conform with the church's preferred format. We then differentiate these edited versions of the songs with the suffix 'FW' as per the screenshot below.

We have noticed that although Proclaim retains the majority of the changes, the option 'Show credits on...' always reverts to 'first lyric slide' (when adding a previously edited song to a new presentation). Our preferred format is for the credits to appear on the last lyric slide.
Although a minor irritation, I presume that this is a bug (and am consequently flagging it as such).
Blessings,
