We have tried to replicate the reported issue, but unfortunately the reported scenario is not occurred at our end. Sample used for testing can be find from below link.
In the above sample after drill down and before animation completes, we have clicked on the category to go back to original data, its working properly at our end. Since we are not aware of your exact scenario, we would like to know the following details, which will be helpful in further analysis and provide you the solution sooner.

If you need to add symbol to the drill down chart, then you can achieve this using seriesRendering event of drill down chart and for text, you can use displayTextRendering event. In this event you can customize the text with respect to your requirement. We have prepared a sample in which on drill down we have changed the shape of data label and customized the text as depicted below. You can change this with respect to your scenario.
