Issue with screener

[prakashmurali123]

I am trying to call screen :
stock_list = Screener(filters, table ='Technical', order='ticker') # Perform stock screening
filters is ["ticker=['CRGY', 'TPIC', 'MYN', 'MMU', 'PMO', 'ARQT', 'MQT', 'NYCB', 'PX', 'KREF', 'PRSRU', 'NSTC', 'PTEN', 'BTWNU', 'BACA', 'OWL', 'EIM', 'ACRO', 'IRWD', 'RMGCU']"]
I only get 18 rows. RMGCU and CRGY are missing.
I am new to the API and maybe missing something. Pl advise.
