I'm afraid that "Previous Versions" keep published only in case of the "Pro" version - the "Lite" s always being replaced by the latest release. Thanks for your comprehension.
Usually, IPR issues are difficult to reproduce. If possible, please feel free to send us your scene (ideally simplified and containing just this problematic object(s)) to firstname.lastname@example.org to check it here. In case of big file size, please use a web sharing service as WeTransfer.
Ideally, if you'll be able to reproduce it on a minimal scene, which you can send us, it would be great.
Thanks in advance for any further comments on this issue you can share with us.
