Advance Filter not working

[Ed_]

I have an advanced predefined filter in Insights Desktop which uses expressions as shown below. When I select a particular filter say moderate which has values (3 and/or 4), the visuals only show value 3 not 4. 

However, I have another predefined filter which allows multiselection of the values, so when I select 3 and 4 they do show up on the map.

So, I am think I am not using the right expression. How can I fix this?

So the solution is to do 

floodfactor = 3 OR floodfactor = 4
