Hello Sundeep......I appreciate your concern and I think many of our fellow writers have this same question. . I imagine you will receive a number of sound responses, many different in nature.
If I have understood this dilemma correctly, it is less the actions of hp and more dependent upon the decisions of Google. We have been bombarded with explanations and suggestions, so it's difficult, for me at least, to really understand this disappointing issue that seems to be occurring more often.
It sometimes helps to check our statistics page to see what symbols are accompanying the hubs that have been effected. In my own experience this happens to me rarely but in each case, I have been able to go in to edit and make appropriate changes and/or additions that luckily solved this immediately..
Be confident that you will be able to find the answers and the corresponding advice to correct this concern. Good luck my friend and have a wonderful day. Peace. Paula
