Another example in en:New_Worlds_Mission:

I wonder if this is happening in all these circumstances, or only in some of them:
a) When an MT not supporting HTML content such as Apertium is used (i.e., the issue may be how bullet points are reconstructed from the plain text translation).
b) When an MT that supports HTML content such as Yandex is used (i.e., the issue may be in the services side).
c) When content is added by copying from the source.

Sorry if my description wasn't clear and screenshots misleading. List of items misses bullets in source column. That is before any MT is applied.

This is actually only the visual appearance, caused by our CSS. Unordered lists are the only ones affected. Ordered lists are displayed correctly and en:New_Worlds_Mission has example of both.
Here is what we have with and without the margins applied:
