MATLAB is correct.
Sis(1).Trading = 'As Is'
Sis = struct with fields:
Trading: 'As Is'
Trading(1) = categorical({'As is'})
Trading = categorical
As is
Sis(1).Trading==Trading(1)
ans = logical
0
If you used a capital I in the definiition of Trading or a lower-case i in the definition of Sis(1).Trading you'd receive the results you expected.
SisLC.Trading = 'As is';
SisLC.Trading == Trading(1)
ans = logical
1
TradingUC = categorical({'As Is'});
Sis(1).Trading == TradingUC
ans = logical
1

Your method works for me:
Trading = categorical({'As is';'bla'});
B='As is';
B == Trading(1)
ans = logical
1
You did have a lower-case "b" in your code. MATLAB is case-sensitive. Maybe that was part of the problem?

We don't need another example. Please upload your data. You can use the paper clip icon in the INSERT section of the toolbar.
As I said above, I can define the variables myself and get your example to work. The key to understanding your problem is to use the data you are actually working with.
Trading(1) = categorical({'As Is'});
v = 'As Is';
Trading(1) == v
ans = logical
1
