The dropdown variable tables are currently lowercase for boards that have dropdowns. They should be capitalized for consistency with the Board Type dropdown.
Checked on OCP 4.4 env with payload 4.4.0-0.nightly-2020-02-02-225006, now the dropdown title texts are all capitalized on Monitoring->Dashboards page. The bug is fixed, so move it to Verified.
