Unexpected warning

[mahmacc]

Viewing the current version of a presentation file currently under development, I get a repeated warning, e.g.
** (atril:320014): WARNING **: 14:50:43.276: Unimplemented action: POPPLER_ACTION_RESET_FORM, please post a bug report on Atril bug tracker (https://github.com/mate-desktop/atril/issues) with a testcase.
I attach the file in its present state
