match date

When I enter the match with the import tool the date and time of the match are NOT entered.

I did some tests

1 i copy the data from calc (libre office) and paste them into the tool, the dates are NOT inserted

2 If I edit the dates before importing by entering the numbers from the keyboard, the dates are entered

3 If I write the date with the keyboard, copy and paste it on many rows, only the first date is inserted

4 If I write the date from the keyboard, copy it, and paste it on each line the dates are inserted.
