Missing Sovryn Rewards

I withdrew my xusd from lending. All good, no issues.
I also am lending rbtc - after my withdrawal of xusd completed - I lost my sov rewards on rbtc. It is showing 0 sov rewards.

Please advise.

I submitted this to https://sovryn.freshdesk.com .

its a bug, there is no sov rewards for rbtc lending.
