Denford Software & Machines

After reloading parameters manually after memory battery failure i cant seem to get the buttons relating to single block, opt stop etc to activate. they seem to be doing something as you can see the bits changing on diagnos screen when pressed. But they fail to light up or activate when in auto mode. Is there a parameter i'm missing or something else? machine is tu150p. Any help would be much appreciated.

I've used these parameters, along with the bespoke 900 ones supplied with the machine and the ones for diagnostics. There are also some 8000 numbered ones listed in the manual, would these have an effect, but I'm not sure how to view or enter them.
