On load the conditions don't work if the setting 'select recurring by default' to no
If you do not have the contribution page setting Select recurring donations by default? = yes, on load all options show irregardless of the visibility condition. Currently, that means the one-time frequency unit is the option that shows incorrectly on load. In my case, $3 and $5 should not show.
Switch to another frequency unit and then back to one-time. These are the options that should show on load. See the difference.
