I am using MATLAB version 2019b. The issue is that the Image labeler session when saved does not save/store the label data correctly. When the saved session is re-opened, the label data loads as annotations/boxes on the images but when exported label data is empty. However, data for any changes/edits made to the images within the current session gets exported fine.
Here is another interesting find: All data is exported correctly from a re-opened session when there are no attributes present. The above issue happens only when attributes are associated to the labels.
Is this a bug with the 2019 beta version and being looked into?

Facing the same issue.
If reopening the session loads my bounding boxes, the labels are stored somewhere. How do I get those labels?
Also, i dont wish to edit all the labels and then export labels in the same session as the number of images are large

This issue has been resolved in MATLAB R2020a.

No... I am using R2021b and I can ASSURE YOU the problem still exists. How can I get my data back? Bounding box is there. Where is the background and pixel data? Everything worked fine all the way to the end. I even saved session, gtruth, and pixel label data as seperate number files to avoid complete loss of data as I have been through this numerous times already. Even the old files will not open with the data where they had been working fine all along. Now all of a sudden it is asking for a place to store temporary data. It never asked for a place to store temporary data before. I didn't move the files. I didn't rename the files. All I did was try to upload the files to drop box. I even saved a backup of the complete work to a USB drive and that won't even work now. We are talking about hundreds of hours of work lost just at the point of submittal.

Every time you save the section the images are updated in '.imageLabelingSession_SessionDat' folder which is a hidden folder you can check it.
