How to Append Tables OLE DB or ODBC error

Hi, I need some help with appending 3 tables together. I am getting this OLE DB or ODBC error when I apply the query.

I have 3 tables : table1, table2, table3

Originally I appended table1 and table2 together without issue. However, once I tried to also append table3, it started getting this error. 

I have ensured all the data types are the same by going to 'transform data' and copying the 'changed type' from table1 to table3 (I did the same step when I appended table1 and table2).

What is causing the error and how do I fix it? All three tables have the same columns and in excel, the format of it all looks the same
