When creating a new version of an algorithm, outputs might disappear

I lately tried to create a new version of the algorithm: https://www.beat-eu.org/platform/algorithms/tutorial/lbphs_features/2 This algorithm comes with two inputs and one output, which are correctly displayed in the last version (2).

When I now try to create a new version (3) of the algorithm, the output disappears. Saving the new version of the algorithm is not possible any more, so it seems to be a consistent issue. Also, reloading the page doesn't help.

I hope that you can reproduce the issue. The algorithm is public.

Cheers, Manuel
