Data Type in Oracle is not translating in SSIS datatype

My OLDB data source in the Lookup Transformation is not converting

When I try to join the colunms it claims the data types do not match the only differnece is the percision.?

ORACLE
select CAST(group_id AS NUMBER(18)) group_id from blah blah table
SSIS data type = [DT_NUMERIC], Percision = 38

SQL Sever data source
SELECT
CAST(PRINCIPAL_ID as numeric) GROUP_ID,
SSIS data type = [DT_NUMERIC], Percision = 18The metadata of the columns being joined should have to match exactly. (same precision, same

scale)
