Please try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help we need more informations about your environment.

Which operating system do you use?

Which version of Lightroom do you use?

Please post the exact version and not only phrases as "recent", "latest" and so on.

Please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item.

There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

It seems that when you open the raw file, you automatically correct the lens. Is there a lens calibration on/off function?

Please post a screenshot of the entire Lightroom window with the image open in Develop.

Make sure that the History panel is visible and expanded on the left, and the Lens corrections panel visible and expanded on the right.

I changed the camera model lens in the lens calibration tab you told me, but it was not solved. The problem is that all image borders in the library are truncated.

Do you have reset the preferences as I wrote in my former post?

[Per Berntsen]

Please post the screenshot that I asked for previously, or at least a screenshot of the History panel.
