json headline not the right and descirption empty

Hello,

Since the last update (i suppose, didn’t pay attention before), concern only amp version post,
the article structured data ‘headline’ is set to : Recette %%title%% %%page%% %%sep%% %%sitename%% (recette is a fix word, the other the default yoast parameters) the non-amp version is good .

And always in article and always only for amp , @id finish with two //
like this : https://myurl/mypost//#article

Same prob in breadcrumb, on the last item :
name : Recette %%title%% %%page%% %%sep%% %%sitename%%

I do some test :
I reverse in 1.8.5 and 1.8.6 and here the headline and breadcrumb are good but description always empty.
i try the 1.8.7 and the headline prob appear.

on this posts only yoast, adrotate, amp for wp, Schema & Structured Data for WP, on theme 2017
acf and autopimize (but i flushed it)

and jetpack (i try with and without it , it’s he same prob)

Some test away in 1.8.6, the yoast settings for meta description with text or parameters are not read and print.

But in the last version and 1.8.7 neither and the headline it, write the snippet without transpose the parameters -> i have : Recette %%title%% %%page%% %%sep%% %%sitename%% instead : Recette mytitle – mysite

Very long but i tried to found why and how …

(i stay in 1.8.6 on production site, link inside the ticket)
Good night
