JP1 Remotes

Some idle snooping just got me in trouble. Far as I recall, this was the sequence:
I was looking at anold Denon file of mine for unextended 8910.
Then I wanted to take a peek at Capn Trips' cool files for extended 8910.
Randomly picked a DC file.
When RM prompted to save my file before opening the second file I answered NO.
The second file opened and announced, in the title bar, 8910 extender. That part is ok.

The rest isn't. So I saved the result as MixedUpgrade. Error log included.

Effectively, we got 2 files partly merged. But only on the DC tab. Not functions. Not buttons. Not upgrade (not 100% sure, I think Denon devices got dragged into the index).
It's kinda cute But I doubt that it's an intentional feature to not clear before new file comes in. Is it?

I would add that on the "functions" Tab, the FUNCTIONS from one upgrade are mixed with the DEVICEs from the other

I'm pretty sure I've fixed this in RM v1.30.

You did. Thank you, Greg
I tried several combinations now, watched the functions, which also were goofy, as Capn Trips said, and all is well.

I have a question about number display:
Would it be possible to show zero values when a subdevice in a combo protocol is zero? It makes no difference to IR or the remote, but the nulls derail me
