Hi,
please, neither provide lsg nor lsq exports, only lss.
Reason: lsg and lsq exports are language sensitive. You can only import them into a survey with the same base language.
So we have to guess the base languagfe of your export, create a survey with this same base language and import your question/group.
Please, help us to help you.
Therefore I only used the linked "old" example.
If you use the webdevelopment tool of your browser you see that the class ".dragdropChoiceList" is replaced by ".sortable-choice" (since LS is bases on bootstrap, version 3.x)
So exchange it and it will be fine.

I avoid saying anything about the idea of ranking "Other, please, specify"
