Javascript Not Saving in PDF Form

[kw56077797]

I'm using Adobe Acrobat DC.

I currently have custom calculation scripts. (In the form property, under Calculate, I have my own custom scripts)

It works fine and when I click preview, the code runs.

However, when I save the PDF, open it in preview and attempt to interact with it, the javascript is not activated.

I then open them in Adobe Acrobat and all of a sudden all my custom scripts are gone.

It seems like when I open it in Preview and attempt to interact with it, the scripts disappear. Is there anything I can do to prevent the scripts from disappearing?

Don't use Apple Preview!

It is not only Mac Preview, is also Adobe Acrobat Reader behaviour on Mac.
