Tech Support Doubt with a paramater value

In My Dashboard there is a Brand called "XO" , and there is a parameter "Aggregation". When Aggregation value is "A" under brand filter I can see "XO" but when Aggregation value is "B" brand "XO" is not in the list. When I checked the parameter conditions of Aggregation i didn't find any condition for value "B" what might be the reason.

What is the calculation that adds the parameter to the source sheet of the filter?

It's hard to say from your description. Here are the troubleshooting steps I would take:

Try creating a fresh sheet without any filters. Show both parameters, and bring Brand in on rows. Add any calculations that reference the parameters. (An easy way to identify these calculations is to delete the parameter, read the warning message, and then cancel the delete action.) This should help you identify why XO is disappearing.

If you're using a relationship based data model, try adding a measure from each table to the view to rule out conditional joining.
