How do I get the Apple Mail app to tell me I have more than 150 emails?

It says I have 150 emails. I'm using an iPad 4 that runs on iOS 10.3.3
I have 4 million emails. My new iPhone displays the total email count perfectly.
My iPad used to tell me the number, but atter the email count mixup a year or two ago (with the introduction of iOS 10), it messed up my email count.
What are some things I can do? I've Googled and looked for YouTube tutorials, and nothing seems to work.
