Single post in PokéDex errors

I noticed a discrepancy between number of Pokemon listed for Alola's summon item and the actual number of Pokemon in Alola's Pokedex on the Pokedex screen, including alternate forms like Alolans, Totems, etc. It says 146 on the summon item screen, however, when I added the Alolan forms and the two respective Alolan Totems to Alola's 125, that totalled to only 145.
