What setting is 'EAP-TLS L-BIT' in ISE

What setting is 'EAP-TLS L-BIT' in ISE 802.1x authentication did not work, so I checked and found that this item was checked in the allowed protocol. Unchecked, 802.1x authentication was successful.

Thank you for your answer.

To explain more
I was trying to change the terminals that were authenticating with eap-tls to 802.1x

5440 Endpoint abandoned EAP session and started new
An error has occurred

I have verified that the settings are checked.
This setting is unchecked by default, but it is difficult to determine why it was checked.

I'm trying to find a way not to change the previous settings

You must verify that this setting is essential for 802.1x authentication.
