Problem using .recent attribute of sys.date parame

问题:

I have question regarding Intent configuration in Dialogflow.

I've found information on StackOverflow regarding ".recent" attribute of sys.date parameter.

The idea is that using value from that attribute gives a date that happened in the past (i.e. "Monday" will be translated to last Monday, not next Monday).

I've encountered a problem when using it with required parameters. The result in date interpretation differs depending on the input:

• has the user provided all required parameters at once
• user has been prompted to deliver missing ones.

Please find example below - notice different dates returned for the same input

Questions:

1. Do you know what may be the problem here? It seems like a bug for me
2. I've searched and I have not been able to find documentation on Dialogflow's or Google's sites regarding ".recent" - do you know where I can find it?
