Merge two rows into one with same columns and add columns values - mysql

Question

I have two queries which return the same row structure in 2 rows:
mc_name ENE FEB MAR ABR MAY JUN JUL AGO SEP OCT NOV DIC TOTAL
TOTAL CANTIDAD 0 0 4 55 28 74 112 175 120 123 0 0 691
TOTAL CANTIDAD 0 0 0 0 0 1 2 3 8 7 0 0 21
With UNION I can return both rows but I need to merge both rows into one and add column values for each column expect the first one which is a reference.
How can I achieve this:
mc_name ENE FEB MAR ABR MAY JUN JUL AGO SEP OCT NOV DIC TOTAL
TOTAL CANTIDAD 0 0 4 55 28 75 114 178 128 130 0 0 712
Both queries, with UNION below:
select
'TOTAL CANTIDAD' AS 'mc_name',
SUM(IF(MONTH(properties.created_at) = 1, 1, 0)) as ENE,
SUM(IF(month(properties.created_at) = 2, 1, 0)) AS FEB,
SUM(IF(month(properties.created_at) = 3, 1, 0)) as MAR,
SUM(IF(month(properties.created_at) = 4, 1, 0)) AS ABR,
SUM(IF(month(properties.created_at) = 5, 1, 0)) AS MAY,
SUM(IF(month(properties.created_at) = 6, 1, 0)) as JUN,
SUM(IF(month(properties.created_at) = 7, 1, 0)) as JUL,
SUM(IF(month(properties.created_at) = 8, 1, 0)) AS AGO,
SUM(IF(month(properties.created_at) = 9, 1, 0)) as SEP,
SUM(IF(month(properties.created_at) = 10, 1, 0)) as OCT,
SUM(IF(month(properties.created_at) = 11, 1, 0)) as NOV,
SUM(IF(month(properties.created_at) = 12, 1, 0)) as DIC,
COUNT(PROPERTIES.PROP_EXCLUSIVE) AS TOTAL
