Hi,

I am working on a technical drawing (in SW 2021) with multiple sheets. When I started the drawing there was nothing wrong with it, but somehow after adding a few dimensions, it 'partly deleted' my dimensions and standard blocks.

The weird thing is that I can see the dimension lines, so only some of the numbers are missing. 

The blocks which are missing are blocks we use all the times and are placed in the Sheet Format layer.

Does someone have any idea how to fix this?

Thanks!

I searched the internet, but I couldn't find a solution that solved the problem.
