netVisual_bubble() skips one of the LR pair

[Alexis-Varin]

Hello, I discovered one bug with netVisual_bubble()

I did the following code :

pairLR.use.up = data.frame("interaction_name" = "MIF_CD74_CXCR4")
netVisual_bubble(cellchat, pairLR.use = pairLR.use.up, sources.use = 4, targets.use = c(1:31), comparison = c(1,2))

Comparing communications on a merged object

Error in subsetCommunication_internal(net, LR, cells.level, slot.name = slot.name, : No significant signaling interactions are inferred based on the input!

The problem is that the interaction is present in my source... It shows up when doing

netVisual_bubble(cellchat, sources.use = 4, targets.use = c(1:31), comparison = c(1,2))
