Observed masses do not show up in BinaryStarModel.corner_observed()

[ayushmoharana]

Hi, I have masses and radii estimates of an eclipsing binary system using radial velocities and light curves. I have my ini file (which I load to the BinaryStarModel) the following way:

mass_0 = 2.834,0.12
mass_1 = 2.612,0.1 
radius_0 = 1.749,0.05
radius_1 = 1.805,0.05

B = 9.92,0.05
V = 9.6,0.05
J = 9.0,0.04
H = 8.88,0.04
K = 8.84,0.04
parallax= 3.2241, 0.02

After fitting for ages, when I try to do BinaryStarModel.corner_observed(), I only see the fluxes and parallax.

How can I check if my masses and radii are being used in the fitting procedure?

Thanks in advance.
