Unusual dip in deflection in construction sequence

Hi,

I have a prestressed voided deck slab girder system wherein I am seeing a dip in deflection at 90 days time step which seems odd as there is no load applied at that time in the construction sequence. There are no temporary strands in the girders I am not using them. Can you please take a look at it and see if you have any thoughts on it? I have attached the PGSuper file.

Thank you
Anurag Jain
