So there are slightly different contexts in those variations...
First, you need to remember that the Fallout Reports are Sequential, meaning all the steps before must be hit, before the next step. In the Freeform table, there is no such dependency.
@yuhuisg is right, seeing the definition of your segment will help.
However, in the Freeform table, you have raw "segment" AND "options" against Visitors
But in the two Fallout Reports, you have the "All Visitors" step above them... however, when you add the segment to the panel, this is impacting the "All Visitors" step, so whatever the definition of your segment is, you've reduced your "All Visitors" from 248K to 83K.. so the fallout will have a different logic applied.
The fact that the number went up is confusing, in the panel segment version, I would expect the numbers to be lower, but it may be something in how your segment was created....
