Help needed in ROC

Dear Sir,

Kindly guide me for the following :

In the  MCA website Under the Head Company  after searching for my  2 private limited companies it shows under the head Company Status that one company is Under The  Process Of Striking Off and the other company is  Dormant Company .

Both the companies have  regular sales tax & income tax returns.

Kindly tell what does it indicate and what should I do.
