The G1 spectral type for PM J04129-0710 from
2014MNRAS.443.2561G
appears to be anomalous, and inconsistent with the other published stellar parameters.
The observed colors (B-V=1.50, V-Ks=4.17, G-Ks=3.27) are consistent with ~M1.5-M2 dwarf,
and the estimated absolute magnitudes using the default SIMBAD photometry (Mv=9.36, M_G=8.46, M_Ks=5.19) are more consistent ~M0-M1 dwarf.
The published Teffs are also consistent with early M dwarf: e.g. Teff=3483K(2022ApJS..260...45D), Teff=3641+-68K(2018AJ....155..180M), 3734+-98K(2023ApJS..264...41Y).
It is probably preferable to adopt one of the more recent, cooler published spectral types that are more representative of the star's published Teff and photometry:
M1
2019ApJS..243...28L
M1
2021ApJS..253...19Z
M1.5V
2019ApJS..244....8Z
