This problem has no connection with my previous post. So I published it when I saw that I didn't find a solution, on a problem on which I already spent 1/2h yesterday. I always spend time on the problems I have on your templates or extensions, before posting a question. Also, I didn't say it was urgent.
Anyway, in this case, I finally deleted my contacts and re-create them with exactly the same parameters. Surprise : the title background image is back.
So, ticket quickly closed.
Regards.

Of course I already checked my email address used in my Joomshaper account, before I let you know this problem.
