.3 Schedule series timer through TV search function

So running Krypton 17.3 with Dvblogic 5.5 backend (because i never ever need to touch it ;-)) and running into the following:

– Do a search of anything that should pop up in the guide in the near future (or past)
– Rightclick/longpress OK on (one of the) search results
– Choose ‘add timer’
– Make it a series timer and press OK.

This will give me a ‘unknown error’. Any other type timer works fine.

Anyone with a 6.x Dvblink backend on latest stable Krypton willing to test the above steps?
I am kinda hoping it’s the 5.5 backend because that would give me a reason to finally install the latest release 😉
