Unable to unfix parameters after fitting with multiple peaks

Description

It seems that if you fix a parameter (in the case I tried I was fitting 2 gaussians and fixing their centres) and then do a fit - you cannot always 'unfix' the parameters.

If you right click on the parameter, you just get the "Remove / Plot" pop up rather than the constraints one.

Basically, what I did was, add a background and 2 gaussians, then do a fit. Then fix the centres. do another fit, then try and unfix the centres.

Loaded WS index 1 of focussedGEM38370_TOF. Fitted three guassians to a region with peak-positioned fixed and was able to afterwords to remove constraints by 'remove tie' option
