Hi Stanislava,
Could you also please confirm the build of Project app? Perhaps a screenshot will be helpful, as shown below.

Could you please provide a video showing the exact steps you’ve taken to reproduce the issue along with the symptom?
In addition, we would like to collect the following information:
- Your OS version.
- Provide us with a sample file, we’ll try testing with

To record a video, you can use PowerPoint. In PowerPoint, click
Insert > Screen recording. Once done, save the PPT and upload it in the cloud storage and then share the link with us in private message. Please click
