I am trying to create an ARToolKit app in iOS with multiple NFTs. I have generated the featured set(.fset) and image set(.iset) of both the images, edited the markers.dat file as well.
When I try to scan the images, it displays the object only on one image, on the image which is declared first in the markers.dat file. If i change the order of declaration of the images then the object is displayed on only the second image(which was declared first in the markers.dat file).
Is this some kind of bug or am I doing something wrong?

There I listed all the steps that you need to check if you want to have multiple NFT working. I did this for an Android example but it should be the same for iOS. Let me know if it works for you.
