There is no 25p just as there is no 30p (actually 29.97p), because neither is an actual broadcast standard or monitor standard. That's what the card is based on. The settings for the Decklinks are the same. 25p and 29.97/30p exist in the camera, because the frame is being captured progressively. But the output is always either 25PsF / 29.97PsF or 50i / 59.94i to a deck or via a capture card.
Although the card itself can be set to 1080p/25 in the system settings, the NLE is based on broadcasting criteria, hence the issue.
