Text size is no longer adjusting

Hello I am trying to edit a cloud I saved a couple of days ago, however it keeps coming up in all tiny words when I visualise, rather than the sizes I set. Under layout I still have maximise ticked and no other settings have changed.
When I go into past saved clouds and visualise again, they are doing the same, all tiny words. Is this a Tagul problem, or mine?
Thanks

Sarah

Dear Sarah,
could you please provide name of the cloud which has this issue?
