How to select multiple contain conditions in a table?

Hi, I'm basically trying to filter my results to remove irrelevant rows based on two string conditions. I've attached the xslx file. I need to know the specific cause when the operating mode is 'critical' and the LOOP category is 'WR'. Basically isolating all the rows in the table where my two conditions are met.

Data = readtable('LOOP Events.xlsx','Range','D2:K370'); % Load excel from specified sheet
%LOOPS = cat(2,Data(:,1),Data(:,2),Data(:,3));

LOOPS = cat(2,table2array(Data(:,1)),table2array(Data(:,7)));%,table2array(Data(:,8)));
LOOPS = LOOPS(~all(cellfun(@isempty,LOOPS),2),:);

substr = {'Critical','SEE','EEE'};
selectedcol = contains(LOOPS,substr);
Cause = Data(:,3);
Select_Cause= Cause(selectedcol,:)

The MATLAB approach:

T = readtable('LOOP Events.xlsx','Range','D:K');

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

T = rmmissing(T) % remove empty rows

T = 186×8 table
