Annotating a group using the webeditor creates HELM the webeditor won't accept

[ClairePA]

Steps to reproduce:

I draw the following molecule

HELM generated is correct PEPTIDE1{A.A.A.C.C.D.L.L.L.V.V.V.C.D.D}$$$$V2.0
I create a group and annotate it.

HELM generated looks fine. PEPTIDE1{A.A.A.C}|PEPTIDE2{L.V.V.V.C.D.D}|PEPTIDE3{C.D.L.L}"Test annotation"$PEPTIDE1,PEPTIDE3,4:R2-1:R1|PEPTIDE3,PEPTIDE2,4:R2-1:R1$$$V2.0

• I clear the canvas contents
• paste the generated HELM from above PEPTIDE1{A.A.A.C}|PEPTIDE2{L.V.V.V.C.D.D}|PEPTIDE3{C.D.L.L}"Test annotation"$PEPTIDE1,PEPTIDE3,4:R2-1:R1|PEPTIDE3,PEPTIDE2,4:R2-1:R1$$$V2.0 into the HELM box.
• click apply
• nothing happens
• I move the bar to the resize the canvas and the following structure appears.

• The fragments are correct and the annotations are retained, but they are not connected.
• I click on the sequence tab and then back to the HELM tab and the HELM changes to PEPTIDE1{A.A.A.C}|PEPTIDE2{L.V.V.V.C.D.D}|PEPTIDE3{C.D.L.L}"Test annotation"$$$$V2.0 which reflects the canvas view i.e. is a set of 3 disconnected fragments.

Retested. I now get the error

when trying to apply the HELM string

PEPTIDE1{A.A.A.C}|PEPTIDE2{L.V.V.V.C.D.D}|PEPTIDE3{C.D.L.L}"Test Annotation"$PEPTIDE1,PEPTIDE3,4:R2-1:R1|PEPTIDE3,PEPTIDE2,4:R2-1:R1$$$V2.0
despite this being generated by the webeditor itself.
