That version of the plugin is pretty old at this point and there have been a lot of important bug fixes and new features since then. I recommend upgrading to LBT 1.6.
LBT 1.5 and above has a component called Clothing by Temperature, which is equivalent to that Legacy component but it can work with data collections. So I recommend using that.
Whatever bug you experienced there, it does not exist in LBT 1.6
