swagbucks tv limit cut short

Some days, my swagbucks TV limit is cut short, sometimes it is ok, but sometimes, like today, it was cut less than 50, which is a HUGE problem, it ruins my streak...
Sometimes, it is cut down to around 100 too
has anyone else had this problem before?
My brother also had this problem, at the same time as I did, but we earned different amounts (he earned more than 50). I am not using any bots to help me click.
