jpa-new-field --entity disapearing on TAB completion

I want to create a One-to-Many relationship. When I type the following and hit TAB, I get the --entity parameter

[Talk.java]$ jpa-new-field --named speakers --
--typeName  --lob  --relationshipType  --entity  --length  --primitive

But if I set the relationship first, and then hit TAB, the --entity parameter doesn't show

[Talk.java]$ jpa-new-field --named speakers --relationshipType One-to-Many --
--inverseFieldName  --cascadeType  --fetchType  --required

Looks like there is an order on the parameters (e.g. if you enter one, then something else doesn't show up), but it's not very clear
