Allocated to a project for just one day?

Hello Grapeviners,

I recently got allocated to a project after giving a couple of interviews but I was allocated for just one day. I received an email from RIGHTS for accesses, confirming my allocation to the project.

But the issue is I was just allocated for one day, and my access has been revoked and now it shows unallocated in Ultimatix. I asked my to-be supervisor and she said it will be extended by PMO. But it wasn't extended and now I am unallocated and have been assigned an RMG.

What does this mean? Did they reject me or what? If yes, then why was I allocated just for a day? Please let me know if anyone faced a similar issue and some advice. Thanks in advance.
