@VsevolodX to confirm that the bug is fixed:

the default application picker logic seems wrong. In standata, we have defaultVersion, this determines the default application version. then each version has isDefault key, which indicates whether the build is default (gnu, intel etc) https://github.com/mat3ra/standata/blob/main/assets/applications/applications/espresso.yml But ave is deciding default application version based on isDefault key.

name: espresso
shortName: qe
summary: Quantum ESPRESSO
defaultVersion: '6.3' #<--------
isUsingMaterial: true
versions:
  #### version 6.3 ####
  - version: '6.3'
    # This sets the default build for each version
    isDefault: true  #<--------
    build: GNU
    hasAdvancedComputeOptions: true
    ```
