records module: random display not working

Hello,

I have a records module on the homepage here

http://www.alkemica.net/

it's the big orange text/quote right under the menu bar

which is configured to display 1 random record from one of my types

but it is always displaying the same record

I tried to clean joomla and my browser cache, disbale cloudfare etc... no luck, still the same record (and I have at least 10 records published for this type)

maybe test if this is a bug.

thank you
