'R summarize problems - totals have values like '2e+04' rather than a simple count

I have a table with several hundred rows like below

Area	Numerator	Denominator	Group
AreaA	1	10	1
AreaB	3	10	2

There are 5 groups numbered 1 to 5. I am looking to create a summary table that just sums numerator and denominator by Group. Code I am using is

#Create table of totals by group
SummaryICS2 <- ExampleBook %>% 
  group_by(Group) %>% 
  summarise(across(-Area, sum)) %>%
  adorn_totals()

Instead I am getting below. Can anyone explain problem and correct code please?
