POKEDEX RELATED BUGS

[Stavd]

Hi,

My account name is stavd and i play in Gold Server...I came back in the game after 5 years and i noticed some bugs concerning my pokedex...I have lost the caught and the evolved data of Sandslash, Exeggutor and Marowak...I have an Exeggutor (pvpable not alolan) and a Marowak in my boxes, and i also have successfully completed Mew, Celebi and Jirachi quests, which proves that i had the caught data at least...i also had the evolved data very early in the game cause of the Love Island and the Legendary Quests...I also checked that the pokedex shows that i have Metwo and Lugia caught data, which is not true...

Secondly, i have completed Kyurem and Zekrom Quest and succesfully caught both mons (i have not caught Reshiram though), i have 350 pokedex evolutions (that number is officially shown in my dex), i have seen all 5 gen mon (495-649) (but i have not Mandibuzz caught and evolved data), but the Wailord still prevents me from reaching Crater Town...

Unfortunately, i cannot provide screenshots...thank in advance...
