[Koha] Basket Groups Not Visible

We have installed Koha 3.14.8 from package on Debian Wheezy. We created 12 Basketgoups for a particular Vendor. However, clicking Basker groups option, it display only first 10 basket groups (with Reopen, print, export as cvs option). It is not showing other two (11 & 12). Can anybody help us to resolve it?
