I have not heard of this, but I am willing to wager that it has something to do with the dynamics of stars in the disk of the Milky Way and/or the theory of Spiral Density Waves. The Lindblad Resonances are locations within the disk of a spiral galaxy where for 2-armed spiral galaxies:
Inner Resonance omega - K/2 Outer Resonance omega + K/2where Omega is the angular velocity of the matter in the disk and K is the so-called epicycle frequency of stars. The epicycle frequency is related to the periodic motion of stars at a given location in the disk compared to their motion relative to a reference frame moving at a constant circular velocity. Near the Sun, the epicycle period is about 175 million years. For the Milky Way, the inner Lindblad resonance is at about 4 kiloparsecs from the Galactic Center. The outer resonance is at about 15-20 kiloparsecs. Between these resonances, spiral density waves can occur. At the resonances, the strength of the spiral density wave orbits the galaxy with the same period as the speed of the matter, and under these conditions, the 'small amplitude approximation' for the spiral waves breaks down.
Van Albada is an astronomer known for 'n-body' calculations by computer of stellar motion. I assume that 'Albada-Lindblad' anomaly refers to the Lindblad Resonance. I do not know what the 'Albada' part of the name is in reference to.
