Getting [object Object]

Hi,
I I have a table with a repeat region repeat feature works well, however some of the database fields are not displayed on the page and what shows is [object Object].

I have lots of repeat regions and this is the first time I am getting this error. not sure what to do as the [object Object] text on the page only appears with only 2 database fields.
Is there anything I can do to fix this issue?
Thanks
Juan
