Not able to auto generate full-path for Fragment's class attribute

Hi Jmix Team,

Recently my team and I have faced a small issue after updating to Jmix Studio 2.6.1, when we are configuring the <fragment class=" "> attribute, it will not generate the full classpath that is needed anymore when we select the desired Fragment class, for example:

In the above image, HeaderFragment appears as an option for me to choose. However,
{FBF6EBE0-1C7B-4385-A719-91CF345D255F}
Once I select it, it will only populate the class name itself and not the full-path (com.infopro.synergy…) as expected. Could you please look into this issue?

Thanks.
