This is a technical restriction of the SSP mode which is enabled automatically from 100k transactions onwards.
You have now two options:
1. Either you switch temporary to CSP mode even if it takes more time to load your transactions then.
or
2. You open a separate tab in your browser and search in the trade list (full view) report for dates. Then you can search e.g. for the amount instead of the date of this transaction on the Transactions page.
