Cannot export to PDF/PNG whenconfig.date_scale = null

When defining

Export to PDF/PNG gives wrong output. But

seems to work. Is it impossible to define templates.date_scale for an export?

When defining

templates.date_scale is ignored…

no gantt.templates seems to work for this matter… Even when settings gantt.templates.task_text

Templates related to task’s text and task’s styling will work.
Data scale related templates are not used during export, we plan to fix it in one of next updates.
