Can't recreate RT table after altering its external file

[githubmanticore]

after index created with exceptions \ wordforms \ stopwords then some of these options changed via alter (cause to save disk chunk with original settings) - drop table does not delete all index files but keeps external files from the disk chunk.
That breaks next call to create the same table .

create table test4 ( title text, tag integer ) exceptions='<this_test/>/exc.txt'; 
insert into test4 values (1, 'a b c1 c d', 11); 
alter table test4 exceptions = '<this_test/>/exc1.txt'; 
drop table test4; 
 
create table test4 ( title text, tag integer ); 
error adding table 'test4': directory is not empty: data/test4
