Hi Nicolas.
I still think this is a bug. Let me explain You why.
On my shared on this thread agenda file(jl_diary.agendatest.org).
There are several categories on the items for being showed on the
org-agenda. But org-mode chooses the last (among the categories) for
showing on the agenda. In my opinion if something is bad my my agenda
file (jl_diary.agendatest.org). It should be signaled when loading the
agenda, as the org-agenda does when something is wrong with my agenda
files, like the one I have shared (jl_diary.agendatest.org).
>> I share my agenda among several devices with different emacs versions

I just use the org bundled with emacs with every of this versions. And
everything was smooth just until 26.1
