Navigation TaskTab missing line

Using V8i Series 10

I  have lost the liner line of the tasktab tool  Picture 1 is what I have and Picture 2 is what I now have,  not sure what to do, tried replacing the UPF file with an older version

tried replacing RPhillips.RPhillips.rphillips.TaskNavigation.xml with an older backup copy.


      the above is my problem all the keys I use all the time (picture 2) for lines Q, Rectangle W and Circles E . shifted to new keys and I sure hope someone can help me solve this issue
