Procesing of SILVADatabse full aling

I am trying to use the SILVADatabase 138.1 a data that i imported like FeatureData[AlignedRNASequences] for my reference database, but when i cant convert this database to DNA seq database directly it seems. Becuse i was using:

qiime rescript reverse-transcribe --i-rna-sequences silva-138.1-fullaling.qza --o-dna-sequences silva-138.1-dna-fullaling.qza

I wanted to ask if need to do some extra step to pass the AlignedRNASequence to a normal RNASequence or if i need to delete the gaps '.' and '-' than comes with the al
aigned database?? At the end i want to filter mi data with

qiime feature-classifier extract-reads --i-sequences silva-138.1-fullaling.qza --p-f-primer CCTACGGGNGGCWGCAG --p-r-primer GACTACHVGGGTATCTAATCC --p-min-length 50 --o-reads silva-138.1-fullaling-trained.qza
