Date validation issue Gamma3 Joomla 4.3.0

[ontarget]

I had the following working in Fabrik 4 Beta / Joomla 4.2.7

• jDate field using Format d-m-Y
  
• isGreaterOrLessThan validation check with > check on Calc Element = DateCalcCommence
  
• The DateCalcCommence Calc element has the following php

$date = strtotime('01-09-2021');
return date('d-m-Y',$date);

so any date entered in jDate field < 01-09-2021 resulted in an error - working perfectly.

After upgrading to Gamma3 and joomla 4.3.0 every date fails validation (irrespective if greater than or less than)
Can anyone else verify this?

UPDATE:
I fixed the issue by using the following date format in the Or Value field:
2021-09-01 00:00:00
