This paper aims to rectify the recent fixed point results on graphical rectangular bmetric spaces due to Mudasir Younis et al. (J. Fixed Point Theory Appl., doi:10.1007/s11784-019-0673-3, 2019). Moreover, we also give the answer of some open problem in the mentioned research related to the Kannan contraction mapping in the space described above with its fixed point theorems.
