Fire Red items not showing up

[beardRage]

Hello, I'm new here. I've been using PKHEX for a couple of months now, but for some reason I can't seem to get items to show up successfully today. I have done it a few times before with no issue.

I open my save, go to SAV and click items. I go through and alter the number of items I want to increase. Note these are preexisting items I placed with PKHEX. Then I click save and export my save and put the save back into the folder. I start the game and no changes take effect. I am having the same issue with trying to add TMs (game corner) and coins to purchase pkmn, although I could just add a porygon. Any assistance would be appreciated, I am using John GBA on Android (where my new current issues are) and mGBA on pc. Thanks in advance

Import your save file correctly.

If the save file shows your changes in the program, then they should reflect in the game.
