[experiments] Configurator gets confused if the user selects a new algorithm for block

If I fork the experiment: https://www.beat-eu.org/platform/experiments/tutorial/tutorial/full_lbphs/1/atnt-lbphs-para/, and then replace the algorithm in a block with a decollapsed parameter set, the platform tells me that the parameters are undefined. I'm not sure this problem is related to the fact there are two blocks with similar version lurking around or it is just the swap that confuses the configurator, when it a set of parameters preset.

Anyways, the expected behaviour would be, to preserve all possible parameters that make sense in the new settings, from the old one.
