"Bentley.Staad not responding" when using notional loads for Direct Analysis

I am using STAAD Connect version 21.00.02.43.

I have been trying to create a staad file for direct analysis with notional loads.However, when opening the file as indicated in the image, 

the software stops responding. This does not happen when removing the notional load command under the repeat loads. I am adding the

staad file for reference.

1263.Analysis_2 - Test.std

And every time, after closing the program as per the snapshot above, when I reopen this file in an editor such as Notepad I find the part defining direct analysis to be deleted.
