table_export column appearing in place of grouping variable column when unit_markup is used

[timothytsai]

I observed some unusual behavior when using a grouping variable and unit_markup:

tframe <- data.frame(
group = factor(sample(1:2, 100, replace = T)),
var1 = sample(1:2, 100, replace = T),
var2 = sample(1:6, 100, replace = T), 
var3 = sample(seq(0, 100, 10), 100, replace = T)
)

# produces a table_export column with factor levels as a vector in each row
tframe %>%
 group_by(group) %>%
select(group, var1, var2) %>% 
 ezsummary(p_type = "percent", digits = 0, unit_markup = "[. (.)]")

# works normally
tframe %>%
 group_by(group) %>%
select(group, var1, var2) %>% 
 ezsummary(p_type = "percent", digits = 0)

Thanks.
