Hi Santiago,
The Support said that they are working on it! 
See this last message that support send to me ( 2 days ago ) !
Hi,
This is our number 1 bug that we are working to fix. Should have a solution in the coming days!
Cheers,
For now the the workaround is using a Custom Form!
Other than Airtable you could use Xano , Google Sheets , Backendless etc!
Hope Adalo Team will solve this issue soon!
Thank you
