Posting the solution as received from Adobe Support Team. Just incase it
helps someone. Issue: 100% entry and exit rate for "unspecified" page
name The entry rate is calculated as Entries / Visits. The number of
entries(Entries metric) as well as number of visits for "unspecified"
page name is 1. So, the percentage of entries(entry rate) will be 100%.
[Same goes for exit rate] Since there is only 1 such case out of 23K
values, you can ignore it for reporting purpose.

rate and Exit Rate applied over it. I see a 100% entry and exit rate
with the value "Unspecified". To find the root cause I broke down
"unspecified" with the below dimensions and the following is what I got"
