The main components of both systems are both binaries with a composite spectra belonging to F-type main-sequence stars, meaning they are fusing hydrogen in their cores.

[3] In 2020, after the inclination of the planetary orbit was measured, the "planet" was found to fall in the mass range of a brown or red dwarf.

It was discovered by using precision radial velocity measurements from the echelle spectrograph installed on the Alfred-Jensch telescope in Karl Schwarzschild Observatory.

[8] In 2020, after the inclination of the planetary orbit was measured to be just 4.14+0.96−0.90°, the "planet" was found to fall in the mass range of red dwarf stars.
