Pressing Tab after a Keyword messes up the formatting

We format our code as follows:

SELECT
<TAB>table1.column1
<TAB>, table1.column 2
FROM
<TAB>table1
JOIN
<TAB>table2
ON
<TAB>table1.column1 = table2.column1
WHERE
<TAB>table1.column2 = 'xyz'
.
.
.
etc.

When I type in a key word (such as SELECT), then hit Enter, then Tab, the formatting messes up. Why is it reformatting the code?

UPDATE: This seems to have been fixed in version 2.0.0.59
