cqlsh DESC SCHEMA generates malformed schemas

[AnuraDev]

i have a small database with like 30 tables (and no data almost) i run cqlsh DESC SCHEMA it exports a schema file.
everything seems ok.
but after i try to restore this schema with cqlsh -f /exported_schema.cql for some tables (the one with extra indexes) i get this error

Error from server: code=2200 [Invalid query] message="Unknown column name detected in CREATE MATERIALIZED VIEW statement: idx_token"

the point of issues is, why the tool generates this code in first place? and this happens after everything is in scylla so has nothing to do with some legacy tables.

if everything is correct exported schemas (on the same server/version) shouldn't cause any warnings because they were filtered before serialization.

maybe this will help to understand the issue, my old cassandra table definition (but this table was reimported long ago so the schema now is different)

"CREATE TABLE IF NOT EXISTS passrecovery (" +
" h text, " + // hash
" u bigint," + // user
" PRIMARY KEY(h)" +
")"

"CREATE INDEX IF NOT EXISTS ON passrecovery (u);"

and here is what the tool exports

h text PRIMARY KEY,
u bigint
) WITH bloom_filter_fp_chance = 0.01
