Hi,
I am trying to setup a table from extracted data from a matrix, but when I create the table I cant add the left stub, the image below shows 4 tables:

table 1 uses ls as the main body and I can add ζ.in as the right stub
table 2 use CSA.in as the main body and allows ls to be added as the left stub
table 3 the same as table 2 but using ζ.in as the main body
table 4 is the issue, here I can add the main body/header, but will not allow the addition of the left stub.
All 3 data sets appear to be the same, where have I gone wrong, or is there a bug?
