For any bug reports please provide the following details as well,

• MC Version: 1.11.2
• C&B Version: 13.16
• Do You have Optifine: Nope

This is unfortunately a known issue for 1.11, this was also reported in #487. I commented the following there:

Could you try removing the chiselsandbits_clipboard.cfg file from the /config/ directory?
Otherwise try setting the configuration option persistCreativeClipboard to false.
