Project Cost budget is missing in Manage Financial Project Plan

Summary:

Dear experts,

We have created a project and loaded tasks using the 'Import Project Tasks' FBDI template and then loaded cost budgets using 'Import Financial Project Plans' and everything seems fine after loading. But, after some time, when we rechecked the project, tasks are there, but the loaded budget are missing. We just see blank as if nothing is loaded for the budgets. Not sure what is the cause of the issue, anyone faces this issue?

Please advise.
