Find and Replace

This is not my first post.  Supposedly the second patch fixed this non working part of 2019.  It only sort of did.  Sometimes I can get it to work.  Once. After it maybe works once, it won't find anything on the next find and replace.  I had to open a file in x8 to work with a client's file, so I could group similar colors and replace the fills/outlines.  There were 8000 little pieces of objects in that file, and 2019 was absolutely of no use trying to clean this file up.  I'm so frustrated that this just doesn't work right.  I know others have no problem with it, but again, it'll only work once or twice, and then I get no objects found.  Do better Corel.
