URGENT! Zoho Report cuts a digit from a number

URGENT! Zoho Report cuts a digit from a number

I'm repeating the problem here, sorry.

=====================
Dear Zoho Reports Team,

We've just found a big problem:

1. We have a query which is created as SELECTs from many other queries and tables.

2. It has the first column 'code' which has Positive number format

There are, for example, two codes:
1242357
1242359


3. I have another query over this query, where i do:

SELECT  concat('810',code) as "code"

where 'code' is the column 'code' from the first query.

4. In the second query i get CUT version of the code.  I've just got:

810124235
810124235

while they must be
8101242357
8101242359


What's going on? That breaks everything and i can't find any reason Zoho does that.
Column 'code' in the second query has Plain text format.

Thank you.
