Clear table settings from previous engine

Clear table settings from previous engine

I running MariaDB and on myisam tables try change engine to aria. After
changing it back, I have some errors with tables. I need to set
rowformat=fixed, phpadmin says ok but format is still dynamic :-/ in
console I get warning:
MariaDB [(none)]> ALTER TABLE test.mytable ROW_FORMAT=FIXED;
Query OK, 0 rows affected, 1 warning (0.01 sec)
Records: 0 Duplicates: 0 Warnings: 1
Table storage engine 'MyISAM' does not support the create option
'TRANSACTIONAL=0'
transactional=0 is parameter from aria engine which stay on table after
change engine to myisam, but how to delete this?
if I make copy of table, settings is copied too...and re-create tables
manually is not possible, this problem affect large amount of tables :(
