sia_request_again on LOST csv annotation file

[TontonJambon]

Describe the bug
A clear and concise description of what the bug is.
sia_request_again on a imported csv file causes SQL error

To Reproduce
Steps to reproduce the behavior:

• I created a folder with 4 images
• I annotated them with a SIA pipeline
• I downloaded an export of the annotations
• Copy the exported CSV file next to the images
• I create a new sia_request_again pipeline and choose the CSV file as data
• The pipeline fails with ERROR

The issue seemed to be that in the SQL request to insert two_d_anno, the sim_class was "nan"

Now I edited my file by hand and add 1, or 0 in this field for every annotation. It corrected the error but now my annotation was causing LOST interface to become blank.

Expected behavior
I would expect to be able to browse the annotations and add some

Additional context
Add any other context about the problem here.
Actually I don't want to really annotate again my data, what I want is to generate a lost compatible dataset out of YOLO/COCO formatted datasets to be able to add a new label to a dataset (I downloaded 1400 images with annotated vehicle and want to also annotate people on this dataset)
I attached both error logs.
lost_annotate_ui_blank.txt
lost_sia_request_again_log.txt
