  Light sterile neutrinos have been motivated by anomalies observed in
short-baseline neutrino experiments.Among them, radioactive-source and reactor
experiments have provided evidence and constraints, respectively, for electron
neutrino disappearance compatible with an eV-scale neutrino. The results from
these observations are seemingly in conflict. This letter brings into focus the
assumption that the neutrino wave packet can be approximated as a plane wave,
which is adopted in all analyses of such experiments. We demonstrate that the
damping of oscillations, e.g., due to a finite wave packet size, solve the
tension between these electron-flavor observations and constraints.
