having a problem vendor AP checks

Is anyone else having this problem?  After doing Set to Pay, I am going to 4-3-2 Pay Vendor screen.  Click on Select All.  Click on Pay Vendors.  When 4-3-5 opens vendors in list is selected but the vendor numbers displayed are not the ones in the list.  I have to delete those and enter all the vendor numbers for the vendors I want to pay.  This happened after I installed version 19.2.  What am I doing wrong?
