Drop-down arrow icon is missing in .ods

[chamdim]

Hails!
I have a .ods file in Nextcloud, and it opens perfectly. I don't have any issues except for a small one, which is not a problem but it would be good to find the reason.
Some cells, when clicked, display an icon for the drop-down list they contain. This icon is an empty square, and the symbol of the drop-down list, which is the downward arrow, does not appear.
Locally edited with LibreOffice shows the drop-down arrow as expected.
Any idea?

Nextcloud Hub 7 (28.0.3) docker
Nextcloud Office 8.3.2

@chamdim think you are in the wrong place. This is the forum for the Nextcloud package on Cloudron. For Nextcloud Hub, you have to ask the upstream community. Somewhere at https://help.nextcloud.com/

Totally noob, my bad.
Thanks for the suggestion. You can delete this.
