FLEXIContent Universal Content does not show correctly

Hello,
I have created a FLEXIContent Universal Content module to display the latest news on top of my articles (position 3 of the Protostar template) in a carousel mode.
It works fine everywhere except when a particular article is displayed; that article contains a code to display an accordion (the purpose is to display a glossary)
This is the code (only the first few lines are shown)

[accordion name="Glossaire" width="800" hideSpeed="500" showSpeed="600"]

[item title="Bibliographie"]

Bibliographie

AGAPAIN. Les meuliers. Presses du village. 77139 Etrépilly. 2002

First image: the normal situation





Second image: what it becomes with the "Glossary" article





Is there a possible conflict between FLEXIContent and the "accordion" extension?

Thank you for your help,
Richard

but it possible to have a js conflict

Hello,

Thank you for your advice.
These errors are reported when opening the "Glossaire" article:







That error does not appear for other articles.

I'll try to dive deeper in the code.

Richard

I checked the following: when i add an "accordion" code to another article the same error appears, there is a conflict between flexicontent and accordion.
The code where the error is detected is the following:
and the error is "Uncaught TypeError: jQuery(...).select2 is not a function"
