I think the solution can be found in your templates. This is the "original" part in the productdetail.template:

<!-- Begin Model Selector -->
[TAG:TEST:<prop TestType="hasModels" Action="Show" />]
<!-- Models Radio Button Selector -->
[TAG:TEST:<prop TestType="setting" TestName="modelselector.flag" TestValue="1" Action="Hide" />]

[TAG:END]
<!-- End Model Selector -->
That means: If the modelselector.flag is set to true (TestValue="1"), a radio button list is displayed, otherwise a dropdown list. The issue could also be some error in the [TAG:TEST...] sections, or these tests are missing.Please regard: this version of NB_Store is no longer supported, the new version can found here.
