Issue with swatches not creating variation after selection

Hi,

I made an import. After that import – so it seems or maybe it was there after the last upodate but did not notice – for some products the variation is not created anymore after selcting all variations. Please assist. I disabled the plugin for now. This effect can be seen with these two examples when the plugin is being activated:

Please assist. Thanks and best regards
