We need more context to understand your problem:
Which science pack are you talking about?
Which liquid do you need to produce, and which recipe do you intend to use?
Which mods do you use – which mods from Angel's and which additional mods?
Can you provide a save we can sync to and load to reproduce the issue?
Does that issue also appear when you start a new game and check the possible recipes in the tech tree?
The version I was referring to is 0.11.16 not 0.11.6. Please make sure that your mods are up to date.
