Taxonomy field in app list

Hello!

I have created an list (Custom List) inside my SharePoint 2013 App (SharePoint 365). The list has an Taxonomy field (Required), when I'm from the SharePoint GUI add an new item to the list everything works fine. However when I'm viewing or editing the same item the taxonomy field is empty and when I'm trying to save the item I get the following message "The SPListItem being updated was not retrieved with all taxonomy fields.
".

Thanks in advance!
