Adobe Reader can't save dropdown list

Hello,

We are using Adobe Reader DC last version (I've re-downloaded it and checked update).

We are currently working with a document wich doesn't behave like it should : it's dropdown aren't properly saved.
When we change one of this field, everything is saved correctly expect the dropdown.

Of course i've tried this problem with a different computer.

What is even weirder is the fact that, displayed by chrome our result are not shown but displayed by edge it is !

What can we do to resolve this situation ? How should we proceed to save the information, keeping the dropdown mechanics but enabling everyone to see that it is being displayed on adobe reader DC ?

Here's a link to download THE file : WeTransfer

I'm an IT guy, so go technical if you need it.

Thanks in advance
