I see you have applied 2 filters: Filter Product and Filter ETD/DO
1. If you want both the filters active:
The caution mark indicates that the filter is not working anymore. This is probably due to the 'Filter Product: Product' line item having dimensionality that does not match the rest of the module. Please check the dimension of this line item and make sure it is the same as the rest of the module (an extra user dimension is ok and will not cause the filter to fail)
2. If you want only the Filter ETD/DO filter active:
Simply click this button highlighted in red and the filter causing the error will disappear along with the caution mark
To clarify the cause of this issue further, let me explain what we did.
The module is testing environment which derived from development environment. Today we degraded the version of dev environment, and then revision tag that is related to the dev environment has inactivated.
