Description
probe_interaction(c.mod, pred = age.6, modx = homecog.c,
center = 'none', digits = 3, cond.int = T, johnson_neyman = T, legend.main = 'HomeCog')
sim_slopes (c.mod, pred = age.6, modx = homecog.c, legend.main = 'HomeCog', cond.int = T,
johnson_neyman = T, centered = 'none')
both above commands resulted in different JN intervals...
Is this a bug or did I do something wrong?

Research direction
Start by reproducing the supplied probe_interaction() and sim_slopes() calls with the same model and arguments, then inspect those function entry points for how each computes the Johnson–Neyman interval. Done means determining whether the differing ranges are expected or a bug, with a clear explanation and a verified fix if needed.
