Magento 2.2.5: Ui-component render wrong position

Question

I am doing rendering students to magento admin page using ui-component after this course

https://www.youtube.com/watch?v=qeIjXiAI5JY&index=3&list=PL98CDCbI3TNvvb0SvN_M35IToppFCHGg3.
And its working. But for some reason, it render in the wrong position, even when i set the sortOrder for theme.

Like you can see, my Age and Choose Column is render in the last position.And also, my Filter and Search is not working.

Here is my code.

Answer 1

Add sortOrder="40" for sorting column. For example

<column name="name" sortOrder="40">
    <settings>
        <filter>text</filter>
        <label translate="true">Name</label>
    </settings>
</column>

Now truncate ui_bookmark table and clear cache.
