Hi @matej.biro,
As of last week's update, we introduced the ability to toggle on\off leading zeros. You'll find the option within the Annotation Settings menu at the bottom of the screen; to the right of the zoom and pan controls. Toggling the 'Display Leading Zeros' checkbox on\off will update all primary and tolerance dimension values across all sheets within the current drawing.

The Display Leading Zero is also included in Preferences > General > Drawings so you can set it as needed for all new drawings. If you are using the ASME drafting standard, we turned leading zeros off by default so we comply with the ASME drafting standard. So maybe, you'll need to turn it back on here. Once you do, all new drawings started from scratch using the ASME drafting standard will display leading zeros.

Hope this helps.
Thanks,
Andrew
