  Recently, several models have been suggested to reduce the tension between
Gallium and reactor antineutrino spectral ratio data which is found in the
framework of 3+1 active-sterile neutrino mixing. Among these models, we
consider the extensions of 3+1 mixing with a finite wavepacket size, or the
decay of the heaviest neutrino $\nu_4$, or the possibility to have a broad
$\nu_4$ mass distribution. We consider the reactor antineutrino rate data and
we show that these models cannot liminate the tension between Gallium and
reactor rate data that is found in the 3+1 neutrino mixing framework. Indeed,
we show that the parameter goodness of fit remains small. We consider also a
model which explains the Gallium Anomaly with non-standard decoherence in the
framework of three-neutrino mixing. We find that it is compatible with the
reactor rate data.
