CL Source editor tabbing to column 56?

RDI 9.8.0.2
When entering a new line of code in a CLLE source member in RDI the cursor jumps to column 56.
The scenario varies but here is an example. I am keying code on a line. I am finished keying on that line. I press the down arrow key to move to another line and the cursor jumps over to column 56.
Another scenario is a use the mouse to place the cursor on a blank line, type a key and the cursor jumps to column 56.
Truly annoying.
Is there something I can do to make this not happen?
Am i the only one who encounters this issue.
(Not an issue with RPGLE or SQL members)
Any help appreciated.
