We have tested it a few times and couldn't get this bug. Please take a look at the attached screenshot - the message is correct after a merger. Could you provide a save game file that we can use to test the problem?2 more thimgs i moticed over and over again.
1. the R&D's after a mrger, will complete properly but the message when R&D is finished is also for a total different product and this incorrect product is then in the R&D center on invention i.e. the corp i did merge into mine did research chalks after r&d is finished i get a message that your caviar production is finished and a new caviar production is started but it did give the research points towards chalks. happened with every single research finished after a merger.
This is already fixed in v3.0.21 (but not yet fixed in v3.0.20 or v3.0.20B).2. the Option to set up a subsidary company does disappear for good after the 1st time you save the game. this is with DLC activated and w/ realworld w/o realworld and w/o script.
Here is a special version v3.0.20B with the bug fixes for your testing:

You can use this version to load your save games as version v3.0.21 will render the old save game files incompatible.
If you still encounter any problems, please let us know.
