Some issues not showing on gantt

[Infraestructura_Aldeamo]

We are having troubles with the plugin, we are using gantts to show in a simpliest manner to other teams the dependency and due dates of issues in a project.

It was working good, but today some issues stop showing... those issues have no difference with the one thar are show. I did verify the project permissions, and statuses. But can't get something that shows me the error.

There are several gantt charts available, so I'm not sure which one you are using. If its still an issue for you I would check that you don't have Issue Security impacting things.

In any case, I recommend searching for any similar issues, depending on what gantt chart you're using:
