Not able to store an Array field from a Structure to another variable

So I have this structure in which one field stores position data which is another array of 5 data points for 20 entities. When I call the structure as StructName.FieldName, it returns all the members (5x20) which is good but when I assign this to another variable, it only accepts the first array and the other 19 are ignored. As shown below, the structure with name F1 has a field with Position arrays as shown.

F1.Position %This returns the entire column properly

Variable=F1.Position %Only the first entry gets stored

Even F1.Position(2) or any other number gives an error saying

"Intermediate dot '.' indexing produced a comma-separated list with 20 values, but it must produce a single value when followed by subsequent indexing operations."

Essentially I want to store that entire column in a separate variable and would love a clean and MATLAB worthy way to achieve it.

Thanks in advance.....

M = vertcat(F1.Position)

or

C = {F1.Position}
