6.10-rc2 Share cache settings not honored

I have an existing Share which I have turned off Caching.   However new files are still being written to the cache for that share.   Also If I create a new share and initially set cache to No, and then go back and set it to Yes - new files are not placed on the cache they go to disk.  

I have not restarted the server, but in the past I've not had to do that when changing cache settings.  

Steps that I can follow to re-create the issue on New Share

1. Create new Share and set cache to No, click apply

2. Change the cache setting to Yes, click apply

3. Share it out over SMB

4. Copy a new file to the share

5. The new file is on the disk

Steps that I can follow to re-create the issue on Existing Share

1. Change the cache setting to No for an existing share that is already set to cache yes, click apply

2. Copy a new file to the share

3. The new file is on the cache

or if you have an existing Share with cache already set to Yes, change it back No and the files still go to the cache.   This is also affecting dockers as well.
