Hi

Greetings
from Syncfusion support.
Upon
reviewing your query, we have identified that you are facing and issue where
the aggregates in the Syncfusion Grid columns are not rendered correctly for
the specified columns. To proceed with a solution, we require some additional
information. So, please provide the following details:

From the shared screenshot and code example, we noticed an aggregate defined
for the 'cantidad' column. Additionally, there are multiple columns with the
same name 'cantidad'. Please explain the use case of this duplication.
2.
Provide the complete Grid rendering code along with any event handler functions
used for the three Grids you are utilizing.
3.
Share the code lines defining the custom aggregate function and the aggregate
column definition. If separate functions are used for each, please share all of
them.
4.
Specify the version of the Syncfusion package you are currently using.
We have
created a simple sample containing three Grids with custom aggregates, where
the aggregates are rendered correctly for the specified column. Please refer to
