Cannot download generator that replaced previously downloaded generator

[Former user]

• download appears in the list When selecting the download tab
• downloaded first listed generator (download was successful)
• list is automatically updated so that the second list of the generator now replaces the first
• selected new first listed generator to download (it appears that nothing happens, no download begins)
• selected new second listed generator to download (download begins and is successful)
• work around is that I have to close the app and reopen it again in order to download
