[NTG-context] issue with module update

Dear list, I have just updated a module named PresVoz. I get the standard directory (https://modules.contextgarden.net/dl/presvoz/) and (https://modules.contextgarden.net/dl/presvoz-{%version%}.zip), but no https://modules.contextgarden.net/dl/presvoz.zip (with current version). So when updating the module, I get it only uninstalled. The two most recent updates (this one and the one before) had this issue. Is there something I am missing here? Many thanks your your help, Pablo
