I'm manually adding mileage, but despite saving each time, some of the entries are not getting saved

When you mentioned that only some of the manually entered mileage are not being saved,  it is possible that too much cache was accumulated on the browser, Lauren. Let's get this working and ensure it will save all your entries.

Cache helps browsers load faster by retaining data that you usually access or visit. However, it can cause malfunctions if the browser accumulates too many of it. Let's do browser troubleshooting to fix it.

Let's use a private browser to start the trouble shooting steps because it doesn't store cache. Here are the keyboard shortcuts we can use depending on the browser you're using:

• For Firefox, press Ctrl + Shift + P
• For Chrome, press Ctrl + Shift + N
• For Safari, hold down Command + Shift + N

If the manually entered mileage is saved successfully, we can clear the stored cache on your regular browser. Otherwise, we can use a different browser aside from the one you regularly use.
