Importing bank statements into Zoho books vs Bank feeds

Importing bank statements into Zoho books vs Bank feeds

I have tried many times going step by step from the instructions and just changing this and that and i cant seem to get my imports to match when imported if it gets that far. I bank with CBA and the feeds seem to be the only way I can use it in books, however add & match is confusing and when an import makes it into books i am then left with double ups... There must be an easier way since it looks so easy... Also how can you delete already imported and bank feeds so I can start over???
