Dear Ratnakar Jadhav,

First of all, imbalance is not an absolute problem. You can do a valid analysis on imbalanced data (proc mixed in SAS, etc).
Second, you should not attempt to balance imbalanced data by removing something else.
Third, Sequence effects are seen now and then. Often they are randomisation failures, and this forum has quite some searchable material on it.

EM.
