Grouped referrers shows incorrect values (v2.16.1)

[sunech]

Describe the Bug

The new Grouped Referrers shows an incorrect count for "(Other)".

For example when I check last 24 hours of traffic:

• Domain based referrers show google.com with 2.54k / 55%
• Group based referrers show Google with 2.63k / 4%
• Group based referrers show (Other) with 61.1k / 95%

Total visitors in the 24 hour period is 4.13k, so it seems like something goes wrong in the grouping causing it to count a lot of non-existing visitors for the (Other) group.
