PHx issue : non rendered in a particular page

Hi, I’m facing something that drives me crazy

I call a phx test :


(this is in a chunk)
[!tarif!] is a perso snippet that create the pl +tarif+ (it’s only a category)

this chunk is called in a page content with nothing else in this content (page is not using RTE)

the output acts like phx was not active
(it returns the whole text chain from the call, and, of course, executes the 2 conditional chunck one after the other)

I tried different combinations of page caching...
Everywhere else, phx works fine and extensively (I use multingual stuff)

Help is highly needed

Thank you
