Data disappears from Transform to Data View

HI, 

I hope someone can help me with this, it is driving me a little mad, and I have checked for everything I  can think of, refreshed data, opened the project again etc, and its the same.

I have a Table Library Usage 2022. which is a summary table with some data in it, with values other than 0.  as can be seen in below image

This is what I expect,   when I close and apply I see the following

All of the data is showing as 0 value, there are no active filters on, the only thing I did was Close and Apply, if I go back into Transform Data, the values are there,  Close and Apply, they vanish again.

Any help will be welcome
