Issue blocking more than a block for day

Hello, first thank you for this amazing plugin.
I am experiencing some problems trying to block more than one block per day, for example, I want to block from 1:00pm to 2:00pm and from 6:00pm to 7:00pm. At the moment it seems to be fine, but when I go to another section as “settings” and later I go back to the daily view of the calendar, the entire day appears blocked.
Is this a problem? or maybe the plugin only accepts a lock time period for each day?

Thank you so much.
