I appreciate you providing us additional details about your concerns, tatweer.

I'll share information about the proper formatting when importing your bank transactions.

Based on your screenshot, you use the backslash instead of the forward slash when separating the date. With this, change the character you're using into a forward slash to let QuickBooks recognize the dates of your transactions.

In addition, please make sure to choose the appropriate date format when mapping your account and select the dd/MM/yyyy. Use this image as your reference:

Moreover, after manually uploading your transactions, consider categorizing and reconciling them to ensure they match your bank and credit card statements.

Feel free to update us in the thread if you have additional questions when importing transactions or other related concerns in QuickBooks Online. I'm always here to lend a hand.
