When merging multiple cells in a Jedox Web spreadsheet. it always retains only the content of the top-left cells from the merged range. Contents from all other cells are deleted without a warning.
By comparison, MS Excel is a bit more elegant in this scenario:
if that cell is empty, Excel looks for (and retains) content in the next cells (left-to-right, top-to-bottom until a non-empty cells is found)
additionally, if multiple cells have content, Excel displays a Warning prompt which the user must first acknowledge (including a Cancel option)
