Kentico API to update settings doesn't reflect in CMS

I'm trying to programmatically update the WIF thumbprint value in Kentico. I've developed a small app that does the following: Get's the valuestring thumprintValue = SettingsKeyInfoProvider.GetValue("CMSWIFTrustedCertificateThumbprint");Set's the new valueSettingsKeyInfoProvider.SetGlobalValue("CMSWIFTrustedCertificateThumbprint", newThumbprintValue);I can see the value being updated in the database. The app returns the new value as well. The problem is that when I login to Kentico CMS (I'm using Kentico 9.0.42 BTW) and check the value in the portal, it still shows the old value.I checked that the app and the Kentico CMS app are both connecting to the same database. What else could it be? Thanks!
