Nothing to Do...
This business visa is expired already and you have used also.
Unable to apply for new visa is a completely different story. Both have no connection.

Unless visa is under process..if you check it will always show this old business visa and it is not a problem. I repeat this business visa is not the problem.

There is some problem or missing documents in your new visa application. Company mandoob can know the reason for rejection. If they say it is due to business visa..then they are trying to cheat money from u.
