Events custom properties not showing up in Dashboard.

Hi there,

I am using pendo mobile  sdk in our android project with below version:-

pendoVersion = "2.19.+"

It is being initialized in application class 

Pendo.setup(this, getString(R.string.pendo_key), null, null)

Now when I am firing pendo events with custom attribute like below -

Map <String, Object> properties = new HashMap<>();
properties.put("File Type", fileType);
Pendo.track("view_tickmark", properties);

Event is being reflected in pendo dashboard but its custom attribute "File Type" is not reflected in event details.

Checked in Android debug logs -

Pendo view_tickmark fired

 File Type application/pdf
