Text "Module 1" is incorrectly rendered as "31/12/2000" in xlsx

[luigiaxl]

For some reason, when exporting to xlsx, the text "Module 1" is rendered as "31/12/2000" date. But when exporting to csv, it is properly rendered as plain text "Module 1".

Please compare the ff screenshots and notice the difference between xlsx and csv in Row 6:
