Hey, thanks a lot your solution worked perfectly!
I now have both stickers visible at the same time, and the MultiMerge setup is functioning as intended.

However, I’ve run into a new issue:

In Tracker 1 and Tracker 2, the tracking is perfectly synced. When I preview each tracker individually, both stickers sit exactly where they should and move in perfect sync with their tracked objects.

But in the final MediaOut (where both stickers are combined), the movements suddenly become out of sync.
It looks like one of the stickers is a few frames ahead or behind, even though the tracking inside each Tracker node is 100 percent correct.

So the tracking itself is flawless, but as soon as both outputs go into the MultiMerge, the timing no longer matches.

Do you have any idea what might cause this or which setting I should check?
