Project backup not copying all used samples?

Hi, I’m trying to make a backup of my main project using the latest transfer backup feature, which creates a .dtprj file, which is a compressed file with the uses samples inside. But when I extract the file just three samples of the dozens I use in the project are saved within the file.

Am I doing it wrong?

Are the non-copied samples ones that are included with the DT?

No, all are samples I have uploaded to the DT, non factory ones. I put them in the “Incoming” folder and within specific folders, may be is there a limitation to the naming of such folders? Like no using spaces?

Edit: naming appears to have no influence over this, some of the samples that are correctly copied are in folders with spaces.

Is working now, no idea what was going on, but everything is nice again. Feel free to delete this post.
