So I caught 2 or 3 Gastly in Cerulean City by headbutting trees,I used up like 10+ pokeballs to catch them.And when I went to the pokecenter to see what i caught,there was nothing there,pokeballs gone as well.Then I tried to deposit other 2 gastly that i caught earlier today and they disappeared as well.What should be done?

Check if there's a text in search box of PC, delete them if there's a text then try check your PC again.

Still did not work,because it was no text and also when I search it by text sometimes one of the ones that i have caught appears and sometimes it doesn't.

Now i tried to put a Squirtle in the PC and same glitch happened... I want my poke back :(

This is what happens when i search them in the computer

That Venonat and Onix should have been 2 Gastly.

This happened to my Snubull and Eggexcute as well from headbutting trees and then "transferring to PC" as well. Is there a glitch in the tree pokemon?

not only the tree poke but i also but squirtle and pika and budew and still nothing appears,but after ,,i think" the 3rd slot of mine was full now the poke that started in 4th slot now appear.
