Custom fields on HubSpot tasks won't save

Further to my post here: Link HubSpot data to Noloco tables

There appears to be an issue specifically with the tasks table from HubSpot (and maybe others but haven’t got round to testing all yet; the main ones such as companies, contacts & deals work fine) that prevents data from being entered into custom fields added in Noloco. For example just adding a text field to the tasks table and then trying to save some info into it will be overridden with nothing shortly after.

Is this something that you are able to resolve on your end, or should I look into adding a separate tasks table in Noloco for project management and keep the HubSpot tasks purely for sales related activity?
