Search and replace Format not working in Office 365 (cant find items to replace)

[Duurs]

I try to replace cell format colors in een sheet and I use the pick the cell format to replace but he isnt finding something. The sheet isnt protected.

If i do exactly the same within a new blanco sheet with a cell prepared same format color its finding it.

How or  why is this not working?
