Can't filter by certain types when grouping by subtask

[Przemysław Ferkaluk]

Hi!

I've encountered an issue with grouping and filtering that I'd like some assistance with. Currently, there seems to be a discrepancy between the available filtering options when grouping is enabled and disabled.

Here's the problem:

1. Grouping Issues: When I enable grouping by subtask, I notice that issues of type "NM - POST/REKLAMA" are displayed on the board.

2. Filtering by Type: However, when I attempt to filter the issues, I can't find the option to filter by type "NM - POST/REKLAMA" when grouping is enabled.

My desired outcome is to be able to group issues by subtask and filter them by type "NM - POST/REKLAMA" simultaneously. Currently, it seems that these two actions are mutually exclusive.

To provide a clearer picture of the issue, I have attached some screenshots for your reference.

Thank you for your help in resolving this matter.
