iOS photo upload doesn't show folder names

When trying to manually save photos from an iPhone to SeaFile the folder names are invisible. It appears that both foreground an background colors of the text are set to white. When a given folder is highlighted by the selection bar, the text can be read as it is now displayed as white on gray. This is observed here with SeaFile server 7.0.5 and current iOS app.

Unfortunately, this issue is still present after updating the client app to 2.9.7.
