The game is using MM-DD-YYYY format for representing the date, in the UK and other countries this is not valid but appreciate for the US it is.
Please add a UI option for date formatting or use local system information for the various OS's to display correct region data.
Alternitavely please implement the international standard for representing dates - ISO 8601. Dates are then formatted as YYYY-MM-DD which is already used by the naming of your capture log files button.

Reason for the suggestion is that messages containing card packs can be missed / deleted due to similar dates e.g thinking cards will be deleted on say 4th May but due to the date of deletion is actually 5th April due to how 04/05 is represented in different regions.
