Selections greyed out?

I use a .txt file to select specific horses in an event, and the rest are greyed out, however following this all selections in all markets are greyed out?

Hi
selection name spelling should be exactly as Betfair spelling
enclose the text file selections in quotes
Australian horse racing selections include the saddle cloth number in selection name.

You can keep other selections active for trading (non-greyed) by adding this as the last line of your text file:
#all_active#


see attached screenshot for an example import from text file

thats what happens and I have my selections fine, but all the other markets are now completely greyed out.

Hi
For your purpose I think it would be better to use a trigger condition:
selections name is in file
