@katebutler not sure if this only fixes the issue for the generic single widget or for all reports? In this case @mattab meant for example the Acquisitions => Overview report.

In 3.11 this was formatted, eg

and in 3.12 this is not the case anymore

The solution for this specific widget seems to work but we usually format metrics server side to have consistent formatting everywhere depending on the chosen language / locale AFAIK. Wonder if somewhere maybe some format_metrics: 'all' or similar is missing for example or if there is some other issue.

BTW also possible for example that the |number filter in a sparkline visualisation template is missing.

Have found and fixed the Twig macro that was outputting the raw numbers on Acquisitions => Overview.
Regarding the single metric view, I've looked into the API calls that it makes and it fetches the metrics both with format_metrics=all and with format_metrics=0. In both responses the integer values are unformatted. format_metrics=all calls $metric->format($value) for the processed metrics only, and also does currency formatting for other metrics if the column name contains "revenue".

@tsteur This issue seems to be happening. Customer is using 3.13.6 and this happens when the language is set to Deutsche

@KarthikRaja1388 this seems to only apply here to single metric view and not to a regular report. Can you create an issue with steps on how to reproduce it? Be good to check if this applies to any Matomo report or only custom reports. If it's only custom reports then we'd create an internal issue.
