What steps will reproduce the problem?
1. Goto Grid2 Options
2. Open Indicators List
3. Click an Indicator.

What is the expected output? What do you see instead?
Trying to fix indicator for inner fire because it is locked in the side-middle indicator. But when getting to that indicator there is no check box for it and the options frame spits out errors.

What version of the product are you using?
v393

Do you have an error log of what happened?
