Bug on the vocable trainer - Instead of edit entry, it brings new list when rotated

Expected Behavior

One should be able to edit entry even on landscape mod

Actual Behavior

When trying to edit an entry, and the screen is rotated (landscape mod), it goes back to create a list again, and the previous entry created would be wiped off

How to produce the bug

Open the app, click on create list, enter the name of your desired list and what you would call columns A and B and click OK. Now click on the Add icon (+) which is located at the button right side. Now here is where you have to edit the entry of the list you created earlier. Create/Edit an entry with the Add button.
After creating an entry, now try creating another entry and rotate screen. Once the screen is rotated,
the entries and the list created would disappear and would now require us to create a new list and start all over again......

PS

Entry is different from list....
