GSTR9 Showing less ITC

In my annual return auto populated data showing less ITC In table no. 8.
Example. As per 3b I claimed ITC of rs. 200000/-. Same is also confirmed by GSTR 2A. But when I tried to file annual return GSTR9 auto populated data showing only 195000 in table no. 8. Pls tell me how to correct it.
