Hi. I am trying to get a graph like this one[1]: for the word "bruised" (Hebrew "ratsats" from Isa 42).

I'm getting two different results in Accordance and Logos, and I'm trying to understand why.
The Strong's key number is H7533.
When I search the NRSV for that key in Accordance, I get 19 matches[2].
When I do a 'morph' search in Logos, I get 19 matches[3]
BUT when I do the "translation graph" (is that what that color circle chart is called?), I only get 13 results [4].
I'm quite sure that this is a problem with me doing something wrong, probably in the Bible Word Study panel. I can't seem to enter the Strong's number there so I tried to get at it the best I could, but I'm guessing that I did something wrong.
Any help would be appreciated.
