Interactive Grid - adding filter for more than one value

Question

I am setting a filter for an IG for Field1 equals 'My Value1'. It works fine but now when I try to add another value to the filter I use Field1 IN 'My Value1', 'Test', whatever was displayed with one filter disappears. I also tried Field1 IN 'My Value1,Test' but nothing appears. I used similar filter in other grids and it worked. I can't find any way to debug it to see what is going on. Anyone can tell me what am I doing wrong?

Answer 1

It is very hard to see in the hint here:

...but the separator to use is a semi-colon ";" e.g.

My Value1;Test
