Jira projects missing

I have 4 projects in "In Progress" stage, they are not visible and missing in the "Board" view, but they are visible in the "Summary" view.

It was normal before the xmas break. Any clues to what might cause it?

Thank you all.

Just to inform that I found a way to go around it but not solving the root cause.

1. Use the search bar to locate to the missing projects,

2. Mark them as "Completed",

3. The projects are now visible in the "Board" view,

4. Move them back to "In Progress".
