Dropdown in Excel 365 versus Excel online

Good afternoon, I am stuck with an odd thing between Excel online versus a locally installed Excel 365.
In the online version I have a file with multiple worksheets. In a worksheet I use vertical search.
The field to be searched for concerns / has a dropdown list. This list is in another worksheet.
In the online version, when clicking on a cell containing the dropdown, this dropdown list is immediately displayed and I can start to tap and the "selection" becomes smaller to what I can click and the other fields are filled with this. Ideal.

However, in the locally installed Excel 365 I do not get a dropdown when clicking the cell and in addition I cannot "continue" to the desired one. So I have to "open" the dropdown list and scroll to the desired one. Is not ideal.
Can someone explain to me what I am forgetting? Or is this a kind of code that is in the online version but not in the 365 version.
My big thanks for thinking along and possibly responses.
With greeting
Erik
