Got error "Could not render this component, see the console" when using Enums(A, B, C)

[dunghydrax]

Describe the bug

Reproduce

Using Enums to declare a dropdown selection

// @Param state query string false "Order state" Enums(A, B, C)

In swagger, It looks like

• Select "A"
• Select "--" -> an error Could not render this component, see the console with emoji appear
  

Expected behavior

• No error when picking "--"

swag version: v1.6.3
I've tested with v1.7.0 but It's not work as well
