Sessions imported via Bookmarks do not show

[DerGolgo]

I had to switch computers and, to that end, exported my bookmarks on the old machine to HTML.
On the new machine, I imported them. The Sessions I had saved in SessionSync on the old machine show up in the Bookmarks Menu under "a" SessionSync folder - every time I try and import them, a new SessionSync folder appears. But none affect the one that seems to feed the window.
I had used the new machine previously, hence a pre-existing SessionSync folder.
I have found I "can" manually shuffle the imported sessions into the right folder to make them appear in the window. This doesn't strike me as something most novice users would be able to figure out. Nor something that really should be happening as such.
At least it doesn't resembled the description I found in the help section.
If nothing else, that section should be changed to reflect the need for further, manual intervention.

Not sure why HTML importing creates a new SessionSync folder. I need to check that but like you described the issue is that the addon itself looks for the very first SessionSync folder it can found. Sadly if there is more than one present all others are ignored.
For Firefox Sync this issue is not present since all folders are synchronized correctly but in the HTML export case it might be an issue as you described. I need to verify if the issue is somehow related to HTML exporting not suporting the Bookmarks Menu folder while importing, or why it does creates a new one every single time.
Thanks for telling me about the issue.
