Why does the metastable form of Technetium-95 have a longer half-life than its most stable state?

I was looking at the isotopes of technetium page on Wikipedia recently, and it seems that the metastable $\ce{^{95m}Tc}$ has a substantially longer half-life (61d) than its most stable state of $\ce{^{95}Tc}$ (20h). Several alternative sources gave the same numbers.

That seems quite peculiar to me. Is it just a general thing that I shouldn't count on the most stable state of an isotope having the longest half-life, or is there some quirkiness there (alternatively, an inaccuracy that got replicated in a bunch of places)?
