Thank you @DaneNagy, glad my discovery helped you.
Since it is effecting more than our system it certainly a bug and I hope it can be fixed.
Removing % symbol from the "Rule name" and "Description" solved it. thanks!
Question: exactly which version are you running?
If you know how/where the error is: please post it here? or the fix?
Sounds quite interesting that a % char in the NAME or DESCR changes the way it works ... can it be that you re-opened the rule and saved again? or that it took some time to re-run the rule via the indexers?
Thank you for pointing, it worked for me on my lighting store.
Mind blowing! That's the solution! Thank you!
Thank you.....!!!!!!!! It works!!
Thank you, that fixed my problems I tried to fix. It was just a simple "logic bug" for me
