Does "older" mean something relevant here?

If you got the CCF from the internet, posting the URL would make it easier for us to see whether it would have some problem with the Universal Browser, vs. you just didn't know to use the Universal Browser.

If you have some problem with the Universal Browser with the CCF you are using and you aren't already using the CCF at

try it instead. It is well organized and has nice clean learns for the Yamaha signal.

The type of signal that the Universal Browser calls "learned" does not correlate well with whether the signal actually was learned. A signal might actually be learned and not be that type or it might be constructed (rather than learned) and be that type. But in that CCF I linked the signals are both actually learned (which doesn't matter to you) and the type that the Universal Browser calls learned (which is necessary for the Universal Browser to accept them).
