The failure to make Tempo Auto the default is worse than weird to me, it is a basic failure of the operating system. It is such a fundamental part of using the keyboard live...and choosing to make it default to Preset rather than the much more flexible Auto is patently obtuse.
But as others have noted, Roland is not going to do anything about it now, so it seems it’s either suck it up...or go to a different brand and then discover what idiosyncrasies they have up their sleeves!
