Bank rules not working

I can’t seem to get bank rules to work.
I have set up a bank rule and imported a bank statementCapture

bulk update button does nothing and I can’t tick any of the boxes except the one at the very top which does not seem to have any effect. I have checked that the bank rule does exist and is saved and that the spelling is correct.

not sure how to troubleshoot this one, the instructions in the articles I have read just don’t seem to work for me.

my mistake - I had my columns mixed up in the import file
