If you add keywords to your profile that do not rank this will bring down search visibility. Search visibility is only a percentage of where your tracked keywords rank.
If you remove all keywords and leave only one with a page 1 rank at position 1 you will have 100% search visibility. If you add four more keywords that don't rank at all you will have a 20% search visibility.
If these keywords fluctuate up and down the search visibility will also fluctuate up and down. So you must determine if the loss is due to adding new keywords that do not rank or they keywords you have been tracking have dropped from their former positions.
