Dashboard indicator limited at 50k

[DataOfficer]

Within a dashboard I have added an Indicator which is bringing in a value based on an Arcade expression. The Arcade expression runs successfully and shows the correct value (in testing this is 83841).
However, the Statistic shown on the dashboard appears 'stuck' at 50k. Is this a known limitation?
(Note, the bottom value shows a reference value of the total number of features in the feature service)

Here is the Arcade expression which when Run, gives a value of 83481 (not 50k!)

var fullname = GetUser()['fullName']
Console (fullname)
var fs = FeatureSetByPortalItem(
    Portal('https://www.arcgis.com'),
    'itemid', // removed from post for sensitivity reasons
    2, 
    ['*'],
    false
);

var filfs = Filter(fs, `Verifier = '${fullname}'`)
Console(Count(filfs)) // returns 83841
return filfs
