On Qlik Sense we have the extension 'Trellis container' (which is part of the pre-installed Visualization Bundle) which cannot be exported in any format (see Visualization Bundle limitations: QSE on Windows or QS SaaS )
What I suggest is to make it exportable (at least as image/pdf), otherwise when used the sheet won't be exportable anymore.
