Unhiding a hidden column in the kobo toolbox server data set

Hello, i recently finished data collection. Four research assistants submitted all their individual completed participants questionnaires and i received them in the kobo toolbox server.

However, i was navigating through the different columns of the data sent in the kobo toolbox server ‘‘Data’’ section, i mistakenly pressed the ‘‘hide column’’ section of one of the very crucial variables of my data.
Currently, i have tried all i can to retrieve/unhide this column but all in vain.

Any assistance on how i can go about this? Thank you.
