DVC version: 0.82.9 and following
reproduced on several platforms, like:

Hi,

the command "dvc pipeline show --ascii" seems to have a bug since version 0.89.9, which does not display the dependencies properly, when there is a branch in a Pipeline.

I created a simple pipeline, which looks like this:

Pipeline with Version 0.82.8

If i use the command "dvc pipeline show --ascii validation.dvc" with version 0.82.8, the whole pipeline gets displayed properly.
If i upgrade my Version to e.g. 0.83.0, the connection between "val.dvc" and the previous Stage is missing. If i use the command on val.dvc itself, the stages "train.dvc" and "validation.dvc" are missing (see screenshots).

Pipeline with Version 0.83.0
