(JavaFX) I have 2 similar TableViews on my main menu, one doesn't actually delete something if I searched for it first

Question

Hey I appreciate any help in advance, I have a main menu where you can search, add, delete, and modify two different TableViews. The one filled with the ObservableList works perfectly but the one with the ObservableList doesn't work the same even though I copy and pasted the code and switched out Part for Product respectfully. With the Products it doesn't actually delete a row if I search for it in advance. It only deletes it from the search list (item shows back up if I go back to the full list).

Here is my main menu controller:

import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.event.ActionEvent;
