Abaqus does not read table data

Hello Everyone,
 

 I face a wierd problem.
 

 I have give abaqus a tabular data for displacement at a reference point. But the problem is, the load data is zero of some time and then it increases linearly. 
 

 But when I run the simulation, abaqus does not read the data from the amplitute tabular info, but starts with  a displacement which is linearly increasing.
 

 Does anyone face this problem?
 

 Thanks,
 Aditya.
