CiviContribute: Cannot clear the Thank-you Date (does not set to null on save)
When editing a Contribution in version 5.36.1, we click on the x to clear the Thank-you Date field. It removes the date and time. But, when we click Save, the field remains with the last-used data/time. It does not saved the cleared/null value. This is true on the latest demo as well.
- Find any contribution. Click View. Then click Edit.
- Click the small x next to the time field to clear out the date and time (or simply erase/delete what is there)
- Click Save.
- View the contribution, and the Thank-you Date is still set to the old value.
It should clear out the value of that field.
