The issue RSRP-233912 was closed because it can' t reproduced by you. I've installed build 2113 this morning and the problem lasts for me. I have mentioned this issue in the following thread
How to surpress warnings from R# code analysis
The problem is, that i did not get the option to supress the warning via an attribute in the Quickfix popup as it was in 5.x. Please reopen the issue.
