iViews not being displayed with AUTOMATIC height

Hello guys,

I created some iViews and changed their property Height Type to AUTOMATIC. It worked fine, since all iView frames were adjusted to the size of the content. However, some days later, the same iViews started to be displayed with a FIXED height. If I check the same property Height Type, they still as before (AUTOMATIC). Could you please help me?

This is such a small issue, but is driving me crazy!

Thanks in advance
