Lost Secondary Saved Loops

Hi, I’ve discovered that when I sync from Serato into Lexicon and then back to Serato I lose any secondary loops I have saved from the original Serato sync.
The first saved loop chronologically will still be there but any others will have been removed.
Is this a bug or is there something I’m doing wrong?

What do you mean by secondary loop? Screenshot will help to clarify

And what Lexicon version are you on?
