When viewing tick boxes in adobe some of the boxes are ticked while others are not however when you view them in a web browser such as chrome they view as expected, is there a setting i need to change to allow this to show correctly?

Unfortunately I am unable to provide this as it's one of my customers documents so would be a breach of GDPR
