@rmorlli,
I became encountering this trouble after installing and the usage of the PHP Filter module for Drupal 8. I located that if I went to configure the block that wasn't appearing and checked the container titled "Negate the condition" beneath the PHP tab, then the block would appear as expected.
Hi,
1. Check following on block config.
In Visibility section
Roles and pages section
2. Go to roles and check your role wise permission and find "Masquerade" section all permission is correct or not.
