FL Studio Channel Aftertouch not detected

The midi channel aftertouch signal is not detected / can’t be used sometimes. Sometimes it works as expected. If it does not work, it is only a Vital problem. When using the channel aftertouch signal in other VSTs, it works. Pitch Bend and Mod wheel are working fine. I tested this with two different midi controllers who both support aftertouch (Arturia Keylab 61 MK2 & Sensel Morph). When opening vital in Standalone, there is no issue.

Windows 10 64bit, Vital 1.0.3 and FL Studio 20.7.3 are used.
