No account of changes on my newsletter.

No account of changes on my newsletter.

Hello,
I have a problem to take account of changes on my newsletter.
When I save the corrections. The recording is going well.
But when I view the newsletter or when I come back to edit it, the changes have not been taken into account.

I redid a second newsletter : same problem.

Here are 2 newsletters in question:
2016-05-24 - TH rappel AG + nouveau vignoble
2016-05-25 - TH nouveau vignoble + rappel AG

Can you fix it?

Regards,
Jérôme Evano
