I think Jasem said it is fixed in nightly. So you either move to the nightly (beta test) build, or wait for the next stable release.

Look at the "Get INDI" menu for instructions on how to change to the nightly build (e.g. under Ubuntu), or build INDI from source after pulling the latest from Github.

If you now have Stellarmate then you can open a support ticket with them.
