Issue

When launching the app, a warning is displayed on the sidebar:

This is due to the text inputs having a key and a value. Ideally they should have one or the other.

• value: allows the text input box to show the current value (ex: the directory you are using) and have it be editable. You can just change the last folder name if the directory you are in is nested. This is the ideal behavior of the text input box. However, the way streamlit runs the app code, you would need to enter a new directory twice in order for it to properly work. This is a known issue for streamlit users and it's annoying. The solution? Use a key instead.
• key: When only using a key, you can properly store the value of the directory you enter, and only have to enter it once. However, the text box will not display anything, and you would have to enter the full path of the directory if you want to change it. So that is not ideal.
• Using both: You get a this warning, which I am able to suppress but it will show up when the app is launched. This almost gets the app to the ideal state. The issue here is that the default directory will not be shown when the app starts, but after you enter a directory it will be shown and editable.

Fix

Wait for streamlit to address this, since it has been discussed in the forums. Implement an alternate solution which is to use a placeholder in the text box, which will display the directory but it is not editable. You would still need to type out the full directory path every time. So far there isn't a perfect solution, but it is a minor annoyance and not a major bug.
