How do I lock a rate for a customer with a repeat weekly schedule?

Yesterday, I locked the rates for a few customers. I'm evaluating to raise some rates, but wanted the lock the rates for some of my first customers. I was able to lock the rates for those I wanted, except for one customer. This customer is on a repeat weekly schedule, and is the only one on a repeat schedule at the moment. Rover mobile app and the website are not showing the option to lock the rates for this customer specifically.

Does anyone could explain if this is normal on a repeat weekly schedule or something else is going on? Thanks for your help.
