I won't go into my usual long technical disquisition about how people making statements like that have no idea of how tuners actually work (and few on gear forums do), but the problem is with the bass, not the tuner.
If your B or E "won't track" on a given tuner but will on another, it's not because it's better, but merely that it artificially and arbitrarily fakes and shows a stable input signal that simply doesn't exist.
If your string is throwing a 20- or 30-cent wow, no tuner in the world is going to make you ever be in tune.
"Garbage in, garbage out." You should watch your bass's output on a 'scope sometime. It's a real eye-opener.
Tuners are rated by users on how well they lie, mostly.
Tuners damp and average trash inputs to satisfy the need of players with no ears for practical pitch to deludedly believe they're "in tune," the very concept of which is both controversial and essentially impossible with guitars and basses in actual practice.
This tuner is OK, though fragile and awkward to use and seems to have slow damping calculation (but this may be a low-battery problem -- I hate devices that run on two AAA batteries

). If you're using it for bass and have "tracking problems" [sic], don't use the FINE setting (likewise on any tuner with the option) and tune from harmonics.
Then -- always -- adjust to practical pitch by ear if necessary.
